Bob, yes, I know about that AMCA discussion and I read it some time ago. In September, in another AMCA thread relating to trans cases, I commented several times about them, including mentioning that the factory apparently machined the vent screw area flat on some cases cast in 1939. I also mentioned there about other things regarding case ID so I know how to tell the difference between 38 and 48. And you, too, posted in that September thread:

http://www.antiquemotorcycle.org/bboard ... trans-case" onclick="window.open(this.href);return false;

But getting back to the possibility of a case having a 57 date code, it seems you believe that a 57 date code doesn’t exist based on you not having found one. Well, I haven’t seen a 57 date code on a BT trans case either but I’m not yet ready to say they don’t exist.

And how is the search going for the article you read by Wagner regarding the stamping procedure for engine serial numbers? 8) Eric

Thank you, Bob. I received an email reply from Wagner and posted it in the other thread (52 Pan case VIN). Eric
