[1937sedandelivery]

Mystery solved (I think).
The number stamped above the inspection opening is: *I8-1634764*, which according to Mac's decoder, is for a 1935.
The number stamped on the rear of the case is: 48-7006, which also denotes a 1935 year.
The cluster gear assembly teeth number also indicate 1935.

So, everything points to 1935. The guy I bought it from wasn't sure of the year.
In any case, I will hold off and try to find a 37 case.

Thanks folks,
