Thanks to all and in particular Bill and Kensal for taking the time to look into this. I hope you can turn something up Bill.

Have looked in my reference books and no mention of this maker. It appears to me to be
a Birmingham gun made on a Scott action. Scott supplied alot to actions to the gun trade
and this gun has the typical engraving and style of 1880's to 1900's mid grade Birmingham
Shotguns. Much better condition than usually seen. There is nothing to suggest it was
made or finished in the US.

Thanks Bill. Well that narrows it down somewhat. I am working on getting pictures of the proof stamps and anything else that might help narrow it down further. I appreciate your help.

More Pics
 

I was able to get a few more pics of the proof marks on the barrel flats from the owner. I am not sure if this adds any more information. Thanks for your continued help.

ok - Birmingham proof marks -

"Not for Ball" indicated choke and was only used between 1875 and 1887

Any idea what the "13" signifies?

that is the bore size

is the other tube marked, is the "2B" in the one shot a 12B?

I thought it might be the bore. I am not sure on ?2B at the edge of one picture. Unfortuantely I do not have the gun in hand. It is in California and I am in Maryland. I am researching as a favor to the owner, and for my own curiosity. Unfortunately I have not been able to get the all of the pictures needed. Still working on that.

12 B (bore) over 13m(muzzle) is an early indication of the amount of choke present.

yup - thats the marks on the "not for ball" tube, I missed the 3M :cheers:
