I am trying to figure out the proof marks on a 20 gauge J.F. Smythe(serial 21855). Dual triggers, light scroll engraving and round knob stock, for those who are concerned about such things.
Rib Marked: J.F. Smythe Darlington & Stockton on Tees
Marks on the barrel flats:
Left (measured .028 choke):
Script entertwined BS under crown (above barrel flats)
Crossed halberds with v at bottom
Crossed halberds with p b c
Diamond with 20 over c
21 (nothing around the 21)
Choke
Right (measured .009 choke):
Same as above without choke
I think it is black powder proof only, made between 1904 and 1925, but I wanted to check with the experts. Barrels appear to be fluid steel, not damascus. I thought the 21 markings may indicate the year of manufacturing.
Am I close in reading the proof marks?
Thanks for any additional information you can add.
