At http://olympus.dementia.org/M-1/ Mark Dapoz has a series of serial #s for
M-System lenses, including the 50/1.4. The earlist 50/1.4 that he has
documented #100361.
I don't know if the serial numbers were unique within individual lens lines or
not. Given that Mark also has M-System 50/1.4 #109735 and a M-System 50/1.8
#127421, I think that the serial numbers are across batches or have
non-contiguous numberinc schemes.
All that not withstanding, your lens is pretty old, in any case.
