Hi, Everyone! Just a general question: Which 1/35 M1 Abrams kit would be best-suited to replicate an initial (1980) M1? I welcome all advice and opinions. Older TAMIYA? Or the the older DRAGON M1A1?

(I LOVE the later DRAGON 3535 M1A1 AIM, 3536 M1A2 SEP, and their latest 3556 M1A2 SEP V2...)

You can't replicate an original series "plain jane" or "slick" M1 with the Dragon kit. The Tamiya kit is the only game in town and even with all its faults does a pretty good job of replicating the prototypes. The (older)Dragon kit is an approximation of an M1A1 and has a number of detail differences- larger turret, something resembling anti skid compound on horizontal surfaces, larger gun, different turret details, etc.

Tamiya's kit depicts an XM1 prototype or very early M1. The blowout panels on the turret roof are trapezoidal in shape, but soon into production, the shape was changed to two narrow rectangles flanking a larger rectangular panel in the center. It's not a difficult fix with some sheet plastic.

The only other M1 kits were the long-departed Esci M1, which had a dreadful representation of the exhaust louvers, and, if I remember correctly, an early Academy clone of the Tamiya item.

Academy's M1A1 kit has an M1 turret shell (except for the blowout panels), and could be suitable for backdating, if you're adventurous (it cannot be built into an accurate M1A1, because the turret is too short).

Hi, Brian! Thanks for your input- I really didn't think that I could use the early DRAGON M1A1 kit, (Not the 3534 "AIM" kit) but I figured that I would wind up using the TAMIYA kit, warts and all...

Hi, Gerald! Thanks Very Much for your detailed breakdown! As far as I'm concerned, the old ESCI M1 was never even considered in entering the equation. I had pretty much made up my mind that I would have to use either the old TAMIYA kit, despite it's various faults, or the ACADEMY M1A1. Even with all my model-building experience, I had to step back, take a breath, and then ask myself:

"HOW MUCH DO YOU REALLY KNOW ABOUT THE M1 ABRAMS?"

Not quite as much as I thought...

So, before posing my question on ARMORAMA, I bought several M1 reference books, finding out that what I want to create, are FOUR DIFFERENT versions of the early M1: The XM-1, the M1, the IP M1, and the M1E1... Having learned A LOT from my new resources, I find that now I REEEALLY have my work cut out for me- It's starting to look almost as bad as my obsession with WWII US M4-series Mediums!!! There are UMPTEEN different ways that one can build US versions of the M4-series Mediums alone!!!

Just to clarify my comment regarding DRAGON's 3535, 3536, and now, 3556 M1-series tank kits, was simply meant to convey my positive impressions of these kits, not to actually consider ANY of them to build the initial XM-1 Trials Vehicle thru the IP M1 versions...

Once again, THANKS, both to you and Brian...

Another question: Have M1A1 AIMs or M1A2 SEPs ever had Mk.19 Grenade Launchers mounted on them? I've seen photos of AIMs and SEPs with supplemental M2 .50 cals mounted on their Turret Tops, atop their main Gun Mantlets... THANKS...

Not to complicate things, but iIIRC there were both short and long turret M-1IPs... 84 short turret models were built before the M1E1 armor was added to create the long turret IPs, which also added the future CITV manhole...

No, I have never seen any Abrams with a Mk.19 on it, nor any TM pics or anything else suggesting it could be done. Why would you want/need to when you can take out any target you need with either the main gun or the TC's .50 cal.?

Any proof for that? I have measurements and photos taken from an M1IP and it still has trapezoidal panels. I have never seen any proof that any other panels were used, until the arrival of two large rectangular panels in M1A1.
Photos are tricky - because of how the perspective works it is very hard to tell in most photos the trapezoid shape from a rectangle.

But it doesn't mean that Tamiya got it entirely right - the real panels had different angles than those in the Tamiya M1 kit. Tamiya exaggerated the angles, so their panels are "too trapezoidal". Real panels were a bit closer to rectangles - i.e. the difference in length between the longer and shorter end was smaller than Tamiya depicted it(and as far as I know have not changed from XM1 to M1IP) and that makes it so hard to notice in photos of real tanks.

Unfortunately there is few (if any, other than the Hunnicutt?...) reference books about early Abrams tanks that correctly describe differences between them and identify them correctly in photos...
Even the just released Tankograd book incorrectly identifies every 105mm gun M1 tank with turret bustle rack, as M1IP, what is wrong, as most of those shown in the book are late production M1s, not M1IPs...
The early tank evolved quite a lot during their short service and most authors don't fully understand e.g. what really makes an "Improved Product" version (actually it was the enlarged/uparmored turret, not minor features like a bustle rack, which was also factory added to late production M1 tanks).

Possibly.
I did a walkaround of the fourth prototype ever produced, and I recall them to be rectangular. I don't have access to my photos right now but if anyone cares (and remembers) I'll check them when I can.

Please do. Funny thing is the person who measured the panels for me a few years ago also was sure they were rectangular... until he started measuring them The difference really isn't that noticeable - Tamiya overdid it.

IPM1s (or M1IPs, or Improved, or whatever) are a fairly common topic of confusion it seems. Let's try to clarify. ALL "IPM1"s had the uparmored turret design of the M1A1. The designation "improved performance" was instituted to differentiate the models that had received improvements to the armor package, changes to the suspension, and regearing of the transmission to accommodate the added weight. It does not signify the addition of a bustle rack. The rack was instituted by modification work order at the end of the initial M1 contract, and was also retrofitted by work order in the field or at depot level. The M1E1 test and validation program had not completed evaluation of the XM256 gun, but the other improvements were signed off and the army either made a change order or cut a new contract for the 894 IPM1 units produced. This was done in part to keep the GDLS production line moving and in part to allow a smooth changeover to M1A1 production in the 1985/86 timeframe. IMP1s are a mix of features as a result of the phase-in of features. Early models had the uparmored turret from the start, but had early M1 features otherwise, like the early style Gunner's Primary Sight housing, short turret rails, and a non integrated bustle rack. (CAT 87 winners 4/8 CAV rode these for example) Late models had the same GPS housing as early M1A1s and integrated side rails meeting up with the bustle rack. No IPM1s had the "manhole cover" cut into the roof, since the earliest M1A1s produced in the 85-87 timeframe also did not have it. A lot of sources have misidentified M1s as IPs solely due to the presence of the rack, and that is incorrect.

When all else fails, look for the identifying features of the uparmored turret: Increased distance between the turret face and the tow cable storage post, The auxiliary sight aperture being a half circle like M1A1/A2 instead of full circle, and the searchlight/equipment mount at the top of the mantelet being bent and not straight out. There are other threads hosted here on this subject that have visuals of the identification points in case i'm not making sense.

Pawel,
I concur with your statement on the blow off measurements and Tamiya's exaggerated representation on their M1 kit. After measuring a 05XX serial numbered (built in 1984) M1 tank in 2007 and found that all three panels are trapezoids with the tops and bottoms of each of the three panels about an inch/25mm difference at the top and bottoms of each of the panels. Additionally, I compared the M1 pictures to those I had of a 00XX serial number (built in 1979) XM1 tank and guess what, both vehicles had the identical panel configuration. I will post the pictures and panel measurements when I get home from work tonight

Amen Brother...

The problem is that too many folks are relying on "what they remember" or "What they heard" from 20 or more years ago... IMHO, rumor and hearsay are not the greatest thing to post on a discussion board where the rivet counters frequent - I am using the word rivet counters as a compliment, so no one take offense...

Those "fittings" on the mantlet are actually for removing it as part of the Support level maintenance or removal of the main gun. One thing that I noticed is that the all of the M1s or IPM1s retained the water can holder behind the loader's sponson box despite the bustle rack has a place for two watercans.

You know, with the wealth (relatively speaking) of new M1 kits on the market, why hasn't anyone stepped up and done a conversion set to backdate one of the existing kits to an M1 or IPM1? Everyone figures there are too many of the original Tamiya kits floating around???

Well for starters, it would require a new turret and possibly a new upper hull (sans the anti-skid), along with new tracks. Probably too cost-prohibitive and not enough demand for anyone in the aftermarket to tackle. A lot of cold war subjects are finally getting some love (M48s, M60s, M103 , Conqueror, etc), but the early Abrams may still be too recent given that it's in its thirties now. It's not yet in that sweet spot where age+nostalgia+relevance= interest by the general market.

Looks like a lot of interest in an M-1 or M-1IP kit. It's long over due and would sell well. There's a lot of former tankers like myself that want a good M-1IP kit.

A few years ago i came into possession of a bunch of IPMS Quarteries from the early 80s that were chock full of really good pics of early M1s, Bradleys, M60A3s, etc., including production line pics of early M1 turrets being assembled. I'd scan and pack them into some PDFs, but i don't know what the legality of doing so would be.

Yea, well, you are about to see them measurements again. As for the late Cold War models, perhaps Pawel an get this "friends at DML to get an IP out in plastic. Not holding my breath but the M113 FoV is suffering from the same lack of "respect"

Ha, i knew it!

For anyone wondering specifically how to get to an IPM1 i offer up my rather old build:

Thanks, those are the pics i remember. I think the only thing that can be deduced is that no two panels measured alike, not even the smaller ones that should have. They're not 90 degree angles, but not nearly as trapezoidal as Tamiya represented either.

The rack was instituted by modification work order at the end of the initial M1 contract, and was also retrofitted by work order in the field or at depot level.


By the way: looking at photos in the new Tankograd book I noticed something interesting: late production M1s (i.e. small turret tanks) had bustle rack factory added and the side rails on the turret were straight at the rear - "connected" to the rack rails. But early M1IP tanks (i.e. large turrets), while obviously also having bustle racks, still had "bent" side rails - with ends welded to the turret sides! For me it looks like those early M1IP turrets were manufactured before those late M1 turrets, before the design of side rails was changed to better match the bustle rails shape.
