I really appreciate the information in this thread. I have pieces of three '31s. An early '31 roadster that is mostly complete and I do have a serial number for. A 68c body only and no numbers. (recessed firewall and three hole mirror). Sure would like to zero in on a time frame for the body number and the frame number. While gathering parts for the 68c I bought pieces to a late Vicki. Cowl, one door, frame (with wire brake rod guides, shocks, steering). Skipped on the front axle because it had the wrong brake drums. Now I find out they are the correct five spoke drums. The body has the body number tag, but the frame number might be a problem. I've found that these cars with the wood sills rusted the top for the frame to the point that much if not all of the serial number is gone. It's kind of neat collecting these parts in the hope of completing them, but failing that making some other car complete. Anyway this thread has supplied me with information I didn't have before. Are there any other sources of the same type of information? I know of the 68c site. How about the Vicki? Thanks. Norm
