I spotted this on one of the model shop websites, and thought that with two kits that it was something of a bargain ...
The kit contains a truck (GAZ-AS1) and a Yak-1b.
The Yak-1b is the Modelsvit / South Front kit, which I'll put to one side for now - I've been tempted to the dark side, by that truck. (If I recall correctly, I did build a trusk once, years ago, the Italeri Opel Blitz.) While there is a Normadie-Nieman decal option in the box, it is not the one shown on the lid.
I've been trying to research the GAZ-AS1, and it seems that the chassis is the GAZ-MM, possibly the earlier GAZ-AA. There was another version built the AS2 on the GAZ-AAA chassis, which was very similar but had six wheels rather than 4.
Having found some scale drawings of the truck, I will have to modify the truck bed and omit a few parts.
A couple of queries I have about markings:
I'm not sure if all Russian trucks carried markings - some had what looks like registration details on the cab doors, and on the back flap(?). These are not clear in all photos.
The kit has instructions for one version (A-3-18-56) as shown on the box top. There are decals for other vehicles on the sheet, including some French roundels (Normandie-Niemen?) that I'd like to know more about.
