Thank you for the replies. When I read Stophels opinion, I thought it made sense, as there were settlements of Swedes in Delaware and I think, Eastern Pa. Perhaps it had been made there. Then I happened to find a discussion on this forum, from 2013, about an unknown wooden patch box gun, that looked very similar to LC No. 36--or the KIP gun. Stophel thought it too, was Swedish and presented links to other examples of Swedish guns, that all look similar. Alan Gutchess agreed with Stophel and said that he had studied other examples and that there was no way in knowing when they arrived in this country.
So-- a neat gun, in its' own way; but I think not documentable to being used here in the middle of the 18th century.
Thanks
