Thanks for the reply. Can you elaborate about 3D printing Please? Say l want a 1940 ford, Where do I get the plans to tell the printer what to make?Pray??? I am a collector of automobiles, but in HO scale. Thankfully I model the transition era set in 1957. Plenty available. Jordan made vehicles in HO scale for your time period, but they are now out of business. I am not aware of any company that makes much for the pre-war period. You may have to look into 3-D printing.
