Can anyone ID this barrel

[Medic187]

Gun (I’m assuming BP shotgun since no rear sight) had a broken stock and looked as though it was found in a barn. Surface rust all over but after cleaning the barrel I found some marks on the bottom and a (I’m guessing) copper ring for decoration. The single trigger was pin type through the stock with a back action percussion lock (seer missing).

Hi,
All of your barrel proof Marks are Belgian and from memory the 16.4 mm would be around a 16 gauge. A lot of low-cost Belgian shotguns were imported for hardware and general store sales, yours being a back action lock I will guess 1860-1920's range. You can see them still being advertised in the early 1900's Sears & Roebuck catalogs They were tools for the common folks and are usually found in worn out and poor condition.
Yours may be one of those.

Thanks,
O.R.
