This neat image of the Mack NO comes to us by way to the Ft. Eustis Transportation Museum Library and the efforts of Mr. Kingston Montgomery Winget.

This is a really great build. I am very interested in these unusual (at least for me) American machines. Thanks for posting this. Great job.

Thanks Jeff. I think my subconscious modeling goal is to fill in all the models (like the Mack NO) not otherwise offered. I certainly have a long way to go!

What was(is)the bridge disc meant to signify? Is it the axle weights of the truck?

It is the total weight Indication, this one indicates the single truck and the total weight ( the figure on top) with trailer/gun.
You may see these indications at bridges to. In the former West Germany they were very common.
The yellow number plates show that it is a restaured vehicle, now registered in The Netherlands and owned by the Dutch Army.

If the bridge disk numbers on your vehicle exceed those posted on the bridge itself then you are under orders not to cross with that vehicle.
Sometimes the disk is not a separate piece of metal but simply painted on the fender but the look, size, color and meaning is the same!
The purpose is the same as the "Maximum Gross Vehicle Weight" signs seen on US bridges today.

Thanks for the explanations, even though the question was off topic.

Simple enough, and a good general topic sort of question that some may not know!

Indeed Mike. Just take Federal trucks for instance :
AFAIK, only the 94X63 COE tractor is available in 1/35th scale...

Believe me I know, I know! As you say the Federal COE is available in resin and that would be my primary vehicle of interest at least to start with.
On a slightly different topic I think any manufacture currently doing a GMC Deuce chassis ought to consider doing a COE with a long load box! Cool stuff!

Modification of Dragon Wagon wheelsets for use on Mack NO6:
Narrowing the wheel drums will; just like on the real thing, allow the rubber tires to look thinner and stand just a bit taller as they should on the Mack.
If you are being a purest, the Dragon Wagon wheel drums need to be narrowed to match those used on the Mack. (This step can be avoided if you are like me - a "close enough is good enough modeler".) Use your best judgement here. Start by putting several cross wise score marks around the wheel drum. This will help you realign the two halves of the drum once the cut is made. Then using a Dremel abrasive cut off wheel go around the circumference centerline of the drum cutting it into two rings. You don't have to be too neat or exact here because most of this work will be covered up later. Now give both sides of the cut a light sanding just to knock off the rough spots and using the score marks made earlier, realign the two halves of the wheel drum and re-glue the two halves back together. In the photo above the wheel drum on the right has been cut, re-glued and a strip of Evergreen plastic has been wrapped around it for extra strength.
Now you need to remove the wheel center from the modified wheel drum. This step will become easier after the first couple of wheels. This requires some drilling, some scrapping with a hobby knife and some sanding with either a large round file or a sanding drum mounted on a motor tool.
Once you are down to a smooth wheel ring you then epoxy the Scale-Link resin wheel center into place and you are done. The wheel center may require just the slightest edge sanding to get a snug fit into the wheel drum.

The wheels/tires from Tank Workshop's M123A1C or M125 kits are perfect for the Mack NO as well. The rear hubs still need to be reworked, but that is all. They will sell them as a separate set as well, for about $30. I bought a set of replacement wheels/tires for my M123A1C scratch-build after the Tamiya rubber tires started to come apart since they were stretched over larger wheels (modified 1/24 civilian truck wheels).
Not mine, but you can see them here.
Mine w/the modified 1/24 truck wheels. (no pics since the change)

In this photo both front wheels and the two spares have had their wheel rims narrowed and had their wheel centers replaced.
The rear tires and drums are still the stock Dragon Wagon sets at this point with the exception that the needle bearing housing in the center of the wheel hub has been added to look more like the Mack.
You can clearly see in this 90 degree side view photo, the front of the vehicle stands slightly higher because the narrowing of the wheel drums causes the tire to stand taller. (Just as they would on a real vehicle.)
I have yet to narrow the rear wheel drums in this photo so they are not as tall as the front tires. However the fact the the chassis stands lower in the rear is easily explained once the weight of the 155mm gun is added to the rear hitch. (As seen below.)

Sure would like to see that in a plastic kit….amongst other trucks that are needed/wanted.

AGREED! Mike, even though you did a masterful job with your Mack No., a plastic kit would be just the thing! Just as we could use plastic kits of American La France vehicles, Federal and Autocar Conventionals and Cabovers, along with International's equivalent of GMC 6x6 CCKWs... The NAVY used a good number of those Internationals, whereas the ARMY kept the Internationals in "Limited Standard" use. A Corbitt or two might be nice as well...
Hm. TANK WORKSHOP for more accurate wheels and tires for use on a Mack no., huh? Good idea! Too bad you have to buy an entire resin kit of the M123 or M125 just to get the wheels and tires. I wonder if TANK WORKSHOP would sell the wheels and tires separately..?

They will and do according to an earlier post.

In the process of gathering parts and pieces to build a Mack NO. I love this old cannon hauler.

There is the possibility that Mirror Models MIGHT, just might, produce a Mack NO sometime in the future. I have offered my assistance and any of my research to Libor in the hopes that this will encourage him in that direction.

A very late and out of sequence modeling note:
On the Mack the differential was mounted off-center unlike the differential on the Dragon Wagon which was centered on the axle so modifications were necessary.
In the photo above the axle housing between the left spring mount and the differential has been removed completely thereby shifting the differential towards the driver's side of the vehicle. Then the axle housing between the right leaf spring mount and the differential has been lengthened considerably using a tapered box constructed from Evergreen sheet stock and then blended smoothly into the overall axle structure using body putty and a sanding stick.
The final assembly of the front axle for the Mack NO6 is shown above.
Please note: In the bottom final assembly photo the mountings for the front leaf springs have been shortened considerably compared to the top photo which was taken much earlier in the building process.
