Leather or khaki? Black metal or green?

Shellback. The kit is very nice. Lots of parts. Some areas are simplified like the roadwheel assembly but I can live with that. Before I started on it I was thinking of getting the Eduard PE set but I'm glad I did'nt. The kit will built up well OOB.Besides HB included PEs that will make it look better.  Fit is good although I have to paint a lot of subassemblies because it will be tough to paint them after it has been put together. 

The kits are nice, like any kit can use a little added detail, but the kit builds up decently.

So hows the kit look ? I've been putting off getting one to go with the AFV 155 mm .

Thanks Bronto. That's all I need to know.

If you get a copy of Ampersand's "High Speed Tractor" book it will answer your questions on the M-4.  The seats were canvas, so they would be a light OD color.   The engine would also be the same OD as the exterior of the M-4.
