These two GMC AFKWX 353 can have "COE" removed from the name to match the other three. COE isn't part of the name, all AFKWX 353's were cab-over-engine.

GMC DUKW-353 like the others. All DUKW's had the same wheelbase

This is kind of pedantic, but I would like if you would change "Mk.1" in this to "Mk.I". Commonwealth vehicles generally used roman numerals for the Mark's until the 1960s-ish, then changed to regular numbers. After a cursory search I didn't find any other WW2 era vehicles with a number rather than a numeral.

Shouldn't have a dash between M422 and A1

Schneider P16 - "AMC" stands for "Automitrailleuse de Combat", it's a description of what it is, not part of the make/model.

I'm not going to do them just yet, but eventually I want to go over all the German half-tracks. The issue is that for some of them (Sd.Kfz.6, 7, and 8 ) the differentiation lies in the model code, like with the Sd.Kfz.6 for example there were 5 different generations of design (Typ l 4, Typ l 5, Typ l 7, Typ l 8, and Typ 9) all called Sd.Kfz.6. While for others (Sd.Kfz.9, 10, 11, 250, and 251), all the different versions were differentiated in the military Sonderkraftfahrzeug number, which is really the name of the vehicle. For instance there were 11 different versions of the Sd.Kfz.250, from Sd.Kfz.250/1 to Sd.Kfz.250/11, with many different sub-versions, all of which had the same manufacturer's code, Demag D 7p.

I was going to suggest listing each model as the name + the model code, which is how I name them in my own files, but there doesn't look to be enough of them on the site for that to be worth it, apart from maybe the Sd.Kfz.7 Typ BN m 11. Plus when I look at other vehicles on the site, all different generations are combined together and not differentiated by model code, so I suppose I answered my own question.
