Hello,

Could use some help in determining year of Mfr and last proof? recently picked up a nice old sxs hammer gun with steel barrels that has Ferlach engraved on external barrels and on barrel flats "Joseph Winkler In-Ferlach" there are various numbers that I assume are proof marks or perhaps serial number any way to tell difference? has number 11837.01, 448,07, and 11369 Any help much appreciated.

Tom
