Help with underhammer rifle ID please

[Nach0papa]

Hi all I’m hoping to get an ID of this under hammer rifle that has been in my family since the 1950s. My grandfather got this (and a few others that I might post) when he bought a house in New Hampshire. Since then they have either been in a basement, garage or mounted over the fireplace at my parents house… So it has not been treated well.

This rifle is small, approximately 41” long.
Barrel is an octagon 23” long, screw in to stock, roughly 7/16” bore (can’t tell if rifled)
Trigger / hammer work
Very slim front and rear sight
Wood ram

No makers name anywhere but several marks on barrel (see enhanced pix).

Any information would be greatly appreciated!

I think you'd get a better response on the Muzzleloader ID section I'll move it over there.

As there has been no other response, I'll add a few comments. Underhammer guns are not my focus, but I do have a few and have handled many over the years. Of all the various forms of percussion firearms, under hammers seem to have more "unknown maker" specimens than any other form. They were really easy to build at low cost with a few commercial parts and limited talent. The type with the trigger guard being used as the mainspring is actually easier to construct than other underhammer mechanisms. Yours was once a typical example . (From the photos, It looks like the hammer might have been abused and the nipple is missing as if someone wanted to render the gun unfireable). This gun being found in New Hampshire is no surprise as most of these were built in the Vermont, New Hampshire, and Maine region. The inlay on the buttstock is a common commercially available part. What is unique are the various barrel stampings. Perhaps some collector has seen these before and can then lead you to a maker... good luck!
