Lou,
Thanks for the larger photo of the barrels. Does Thad Scott put his mark on everything he “imports”?
Is this the gun listed as Lot 1346?
http://www.proxibid.com/asp/CatalogPrint.asp?aid=5142Some of the visible proof marks would date the gun to between 1904 & 1954. Working from memory - I think the actual chamber length being marked (i.e. 2-3/4”) appeared in 1925 (perhaps someone can confirm this) so that puts the gun in the 1925 to 1954 bracket. In reality more like 1925 to the early 1930’s.
Shot & ball guns would generally be stamped “S&B” as part of the proof marks – does yours have such a mark?
You'll enjoy playing with it!
Regards
Russell
