In a previous posting (Category: PROTOTYPE INFO/SHERMAN TANKS) I lamented the fact that there are very few prototypically accurate Sherman tanks offered in HO (1:87) scale.

But the good news is that there are quite a few very accurate other models of WWII U.S. military vehicles. If you like to build models as I do, Alsacast (https://www.alsacast.nl/en/military-h0/tanks-vehicles/) offer cast resin kits with fine detail. My source for Alsacast is Small Scale Hobbies (https://www.smallscalehobbies.com). I find them to be very reasonably priced.

I consider the following models to be very accurate right out of the box and very suitable for period flat car loads:

8775.204 M3 Lee medium tank (https://www.alsacast.nl/en/m3-lee-medium.html) and 8775.203 M3 Grant tank (M3 version made for the British Army – https://www.alsacast.nl/en/m3-lee-grant.html)

Grant tanks loaded onto NYC 499135 70 ton flat car at the Pullman-Standard plant.

8775.149 M3A1 Halftrack Ambulance (https://www.alsacast.nl/en/m3a1-halftrack-ambulance.html) – actually this can be any M3A1 halftrack and with the tarp up is particularly good for a flat car load.

8775.122 M5A3 Stuart Light Tank (https://www.alsacast.nl/en/m5a3-stuart-light-tank.html) – actually this is an M3A3 Stuart which was mostly supplied via Lend-Lease to Allies. The separate open hatches can be closed for rail transport.

From the factory, these were mostly supplied with sand shields (fenders) which would need to be scratch built from styrene strip.

8775.120 M5A1 Light Tank (https://www.alsacast.nl/en/m5a1-stuart-light-tank.html) – widely used by U.S. Army and provided as Lend-Lease to Allies. The separate hatches can be closed for rail transport. From the factory, these were mostly supplied with sand shields (fenders) which would need to be scratch built from styrene strip.

I think the Diamond T trucks from Wespe look very good (https://www.wespemodels.com/military_models/military_models_scale_1_87/scale_1_87_diamond). They offer cast resin kits and built-ups. They are on the expensive end. I have two of their Diamond T 968 4-ton 6×6 Cargo Truck #WES 87082:

Roco has/had a nice steel cab GMC CCKW 2-1/2 ton 6×6 cargo truck, but are hard to find and somewhat expensive. An alternate is now offered by ADP Modelle. But it is the Studebaker US6 2-1/2 ton 6×6 cargo truck (I got my two from Small Scale Hobbies). The US6 was mainly provided as Lend-Lease. The model looks quite good.

If the Roco Dodge WC-52 4×4 Weapons Carrier can be found, it too is a nice model even though it is probably over 50 years old. I have recently built two with extra detailing – scratch built windshield, foot pedals, gear shift, transfer case, and parking brake levers, dashboard detail, Sylvan mirrors and a folded tarp in bed (tarps were often taken down as they had a habit of flying off while on a speeding train).
