I have not seen/handled an Indian made flint of any configuration but would suspect that, for all intents and purposes, they are likely more suitable as a wall hanger than an actual usable shotgun. There was a Keith Casteel sxs flint on guns international perhaps a year ago for $10,000 USD. I have a buddy with an original French sxs flint for sale. It rather large for its size (20GA) which is somewhat typical of French guns. I think he wants $3500CAD but o may be mistaken. I have 2 sxs flints, one, a typical low end 20ga circa 1790ish and a 12ga that I made. Also have a pair of William Smith locks that I was putting together to make another sxs but they are yet incomplete. I also have a set of castings (from TRS iirc) for a matching pair of flint locks tho put together for another sxs. I have a couple nice blanks that I bought years ago from Chris Laubach 3”wide for these two sets of locks but got out of gun building years ago so all this stuff just sits waiting for me to get interested again. Lewis Drake and associates always has some nice quality sxs flints for sale but they only deal in high end merch so while you will get a quality piece, you won’t get it for a song.
