Good golly. Some of you guys should listen to the guys that have actually handled this type of gun and have decades of experience .
Mike, I still want to know what you mean by "this type of gun." Do you mean you've seen a bunch of American guns that resemble English guns, with all the mountings etc? That is why I asked for examples. Not because I think you don't have them, but because I want to see them. The subject interests me as a historian.
This gun to me looks like a stylistic hybrid. An American-built hybrid as you correctly say. Many English features but a long bbl. The lock came from an importer who also served the fur trade and specifically the American Fur Company through St Louis.
The WG Chance I posted also appears to be a hybrid. WG Chance was in B'ham and exported to a NY office he set up, then forwarded to St Louis including to the AFC. The WG Chance rifle has English features except the stock drop is really steep, and the crescent plate appears to be converted from a flat plate. I think English wood. It was auctioned as a B'ham rifle but maybe it was American too, with an imported lock.
The Maslin-locked English-style guns I posted are either American like the OP, or English built with Maslin-marked locks. He was another importer of B'ham stuff. And active in Phila. concurrent with Tryon. Was he an AFC supplier too? I don't know.
That's why I want to know if by "this type of gun" you mean you are familiar with a body of English or American guns having hybrid features, or both.
When JJ Henry marketed "English pattern," was he influenced directly by actual English sporting rifles? Did AFC see actual Brit rifles and request "English pattern"? Or were there hybrid rifles by fur trade suppliers like Tryon, WG Chance, possibly Maslin, that were intermediate designs? WG Chance actually was English.
I'm asking because somehow America goes from longrifles in the 1820s to plains rifles in the 1830s in the same time frame. And I suspect JJ Henry was not the only intermediate step.
It's a huge shift and an important event in the history of longrifles. This is a longrifle forum.
If it sounds like I've challenged you, that is only because I want to find out what you know. You say you've seen a bunch of stuff. What stuff?
RAT: relax, nobody called this a Tatham. I posted photos of hardware on a Tatham as examples of typical English mountings. Anyway Tatham was London and much higher quality. Even his military contracts.
