Like any kit, some people will find shortcomings in the AFV "Cent" and others will build it out of the box and love it.
And like any kit, it's not perfect.
That said, it is very difficult to present a kit as an "Australian Centurion in Vietnam", as they were essentially ever-evolving, and each one was different in many small details.
The standard tanks that landed in 1968 complete with side skirts were very different from the "lean and mean" tanks that returned to Australia in 1972 minus fittings such as the smoke projectors and with reinforced hull stowage boxes and new track guards fabricated from 1/8 sheet steel.
While many of the mods were uniform, there was the factor of field repairs, the whims of individual tradesmen and the availability of materials.
What the kit essentially depicts is a tank in late 1968/early 1969 with the bazooka plates removed and spare wheels mounted on the reinforced glacis plate.
You could also quite easily depict an earlier tank by installing the glacis with headlight mounts which is supplied with the kit, or really turn the clock back with a set of bazooka plates (the Aussie tanks only ventured out once - Operation Pinaroo in 1968 - with the side plates installed).
Sure, you can't build a "later" (1969-1972) tank out of the box, but the modular design which includes separate track guards makes the job a lot easier.
I am yet to break out the slide rule and tape measure (and I doubt if I ever will), but the AFV offering definitely looks a lot more like a "Cent" than the old Tamiya offering ... the major differences I have noted is the turret is longer, hull wider and tracks guards narrower.
The rubber band tracks - which seem to be impervious to every glue known to man - have been installed on a Tamiya Mk3 I converted (as best I could) to a 5/1 back in 1991 (Readers of Australian Defender magazine may remember it from the first issue), and I am currently tinkering with the individual track links.
The turret mesh is not incorrect (there were several patterns), but I liked aluminium architectural diamond mesh, which was more convincing, and had the added bonus of making the basket rock solid.
The wheels to me are a complete mystery - to my mind, if you're going to provide rubber tyres, they should be just the tyre, and not incorporate the metal rim. Even if you can get this material to accept paint, it seems inevitable that down the track (pardon the pun) either the paint will flake and fall off or the tyre will shrink and crack.
I've opted for the Legends set of wheels (you need to trim the axles off level with the extremity of the inner hub to line them up with the front idler and rear drive sprocket) and resin items from Mousehouse Enterprises for the spares on the glacis.
I am trying to depict "The Very Diabolical" (call sign 4C) in late 1971 with reinforced bins, sheet metal guards, mud scapers and angle iron guards for the aerials. While the markings for the rear of the hull and turret basket are most probably correct, the nickname for the barrel is not supplied, and my research suggest ARN 169108 was in fact the "Iron Outlaw" ... stay tuned on this research.
I have a great snap of The Very Diabolical taken from another tank from the port side ... although no mud scrapers are visible, they may have been added with the onset of the wet season (remember what I said about ever-evolving?)
Replacing the guards is a simple affair and the resulting shape is far more utility and streamlined than the standard kit.
Firestorm Models' update kit is a Godsend for the mantlet cover and reinforced stowage bins alone. I didn't use the glacis plate because I just couldn't get it flat ... I was quite happy with the miliput weld bead I added to the kit item.
There is some talk about the position of the spare wheels, but there appears to be some variation from tank to tank with the wheel on the driver's side generally lower (originally this was a field mod, but was probably later standardised).
But all this is just me being fussy (or obsessive?) ... as a no brainer project, if I ever did build the AFV Cent "out of the box", about the only change I'd make would be replacing the wheels and the turret basket mesh.
I would post a pic of my ongoing project, but I am currently compiling an article for a major modelling mag, so some of you may get to read about the whole saga in a few months.
