Gunwolf

Hi Gunwolf! Thanks for your efforts. Thusfar everything that I have looked into points towards Sweden - when you put it all together.
1. The simplified Swedish crown with cross above which is a very close match to the one on the gun.
2. The stamp "choke" - is exactly the same in Swedish.
3. The stamp "stil" repeated four times means "style" in Swedish.
4. The stamp "ful" is simply an abbreviation of "fullst�ndig" in Swedish and commonly used that way.

Questions remain:
- The 12C inside diamond - I thought this was exclusively an old Birmingham proof mark...
- The juxtaposed letters that appear to be T and M under the crown...

Here is a great link for marks:

(unfortunately it's not there).

I found this "T" mark under youguslavian proof marks...
Curiously they also used the stamp "choke"

I was able to detect the number 13 on the barrel breach stamped under the extractor...
any ideas what this could mean?

Probably the original bore diameter: .719 vs the 12ga standard of .729.

Yes, I would agree with Mr. Brown as it is more than likely one of the vulgar fractions, 13, 13/1, etc. Odd location though.

Kind Regards,

Thanks for the info.
Does this provide any new clues at all as to the origin of this piece...? I believe the only time I have ever seen shotguns stamped with the original bore diameter was on vintage English shotguns...or I am I incorrect about that?

Not just English guns. I owned a Sauer 20ga from the 1930's that was marked 19, and was indeed overbored compared to the 20ga standard .615 bore diameter.

So...in this case it was originally under-bored (13) and as they drill the barrels and develop it into a 12 gauge some of the steel is removed? Makes sense - If it is over-bored like you Sauer what do they do? Add steel into it? I don't get it?
Anyway...what I was wondering actually was ----- if it is common practice to indicate original bore size on barrels - obviously English, apparently German - any other countries? What period of time specifically...?
Thanks
