Ted,
About the date codes.
My 17 is a two barrel set, a 26" & a 30", both serial numbered to the gun, 117XX.
Both are marked on the left side, below the address, with the choke (MOD & FULL), a triangle, the serial number and S, a sideways wide U (almost like a big horseshoe but it might be a D) and a 3.
The 26" is stamped D(?) S 3 and the 30 is stamped S D(?) 3.
However the serial number on the frame (in front of the loading-ejection port) has a BO stamped above it.
Is the BO the date code? I doubt it as O wasn't used for a year code.
And S wasn't used for a month code. So would DS be the code for Sept., 1925?
