Here's a link to some pics of a nicely restored M3A1 for sale now on Ebay. The only inaccuracies I could see are under the hood. Namely the spark plug wires should not run thru a flex radiator hose and the carburator is from an M8/M20, so the crossover tube to the air cleaner is incorrect. This is a nice basic Scout Car. Hope this will help with your Hobby Boss kits. Randy
Two more links that may help are at my Photobucket account. One has detail shots of various components and the other has pics of my unrestored M3A1, which I hope to get serious about this year.
