Thank you all for the information. I have taken some pictures and am posting them for you to look at and hopefully be able to tell more about them.
I have lots more pictures and if anyone is interested in more please email me at email@example.com
and I will be happy to send them.
I posted 2 pictures of the 16 ga, 1 of the 10 ga showing proof marks on the barrels and 1 of the Semple Kentucky showing the stock.
I also have several antique rifles:an ORIGINAL Alexander Henry, a Turner 4 bore, a Collins rifle w/beautiful damascus barrel in .69 cal (14 bore?) and a Springfield musket probably put together by Bannerman in like new/unfired condition but not all matching parts for a type I or II, some of both.
Also Rifles made by Don Brown: 2 Kentucky flintlocks, and 2 Alexander Henrys.
Plus there is some civil war leather-cap and bullet pouches, buckles, belts, holsters, musket tools, 1873 pattern bayonets, antique powder flasks etc.
Anyone interested just ask!
