I model 1943, and info on the Tennessee Highway Patrol during WW2 is very scarce. I know that they used an all-white paint job as late as 1938, but maybe they went to black fenders during the war, but I can't be sure. Anyway, this will do for now until I know for certain (I can always paint the fenders later if need be).
I still don't know the colors of their uniforms, though, so I have no scale troopers yet.
Really, I think it'd be highly unlikely they'd have been this far up in the mountains in that timeframe. I doubt they go up there now for anything even though it is a state highway...
When the layout was still in the planning phase, I painted a grouping of GIs, including an MP in class A uniform, but they were 1/48 scale and they're just too small for the 1/43 scale figures I have along the front of the layout. Maybe someday I'll place them along the back edge for forced perspective...
