So much for OTB.

The M3A3, for rear deck reference (M3A3s and M3A5s were identical except that the A3's were welded and the A5s riveted)

And Toadman's pictures of an M3A5 Grant for rear deck references as well.

I'll have to scratch build the rear deck. That means throwing in an engine, which would be my first. I wonder if one even exists (the M3A3/5s shared an engine with the M4A2 and the M10, so it shouldn't be too hard). Alternatively, I'll just make a flag out of Milliput and drap it over the deck. That would be easiest and cheapest.
So is there any particular reason the US military had three vehicles named the M3, the half track, the Stuart, and the Lee?
