I have a Perazzi TM1 that is factory engraved. It is one of the early Ithaca guns. I am trying to figure out what upgrade this shotgun is by looking at the engraving. Do any of you know or have access to the engraving patterns that Perazzi used on these early guns? The serial number of this shotgun is 3 digits. I would appreciate any help I can get from you.

Regards,
M. L.
