The Muncie transmissions have a number of unique stamp identifiers on the top rectangular boss at the rear of the top of the maincase. I have an understanding this is possibly an assemblers/inspectors stamp when originally put together?? Has anyone compiled a list of the different ones? I have seen a square with diagonal line and a diamond. I think there are many others as well. Is this stamp attributable to a single assembler/inspector?
There also seems to be a single letter stamped near the countershaft hole on the case fronts-any ideas on these?
