I posted previously on a 1931 Buick Model 94 asking for help decoding numbers. We have been moving the vehicles (and parts)(and more parts), hence the delay. Mr. Corbin said the engine number before did not match, and he was correct. That was a cast #.The stamped number by the oil filler is 2708593. If someone could give me their thoughts on that. In addition, we also came across another 1931 Buick--Model 87 I think. I would appreciate anyone's thoughts on this as well. The stamped # by oil filler is 2735356. A cast # on upper motor is 1248873-3. Under passenger fender is 2583724. On a plate on the firewall is the following: Fisher Body Detroit, Michigan Job # 31059 Body#12735 31 Mod 8-87 Also, on the axel is 1913299. A couple of general questions. What books, literature etc is available for these cars, and where is the best place to start looking? Particularly the Model 94. Seems to be a rare beast, eh? I sincerely appreciate any help you might offer. Sam
