FYI - as far as touch holes being drilled and being proofed - it depends upon from you buy it. Not all Indian or Italian, Spanish etc come from the same shop.Like anything it depends on whose buying it.
I know a little more detail about some historical firearms than someone who does not. So, when I see an Indian Made Brown Bess, Or Charleville or Baker Rifle all i really see is a mess.
Incorrect shaping of the entire gun and its components.
Incorrect wood, Teak and South Asian Rosewood is just way too hard and closed grained for gunstocks.
Locks often are made poorly and require tuning and reworking to shape the parts.
DOM (drawn over mandrel) tubing is not a type of barrel design I think one should not consider of the highest quality, for a few reasons. it’s basically a sheet of steel hammered into a tube and then welded. The welding that closes the seam needs to be done to perfection or the gun could fail at the breech or at the muzzle. While the originals were made this way, they were done with extensive proof testing, as there was an actual failure rate, not all barrels made it to the field. And on Indian guns….. the vent holes are not even drilled.
I have an original flintlock pistol circa made in India for the East India company - it uses rosewood. It by the way was made by a shop the East India company had Manton setup. It even features a captured ramrod before Tower started using them. Is it graceless in form - yes, functional absolutely and I even shoot it occasionally. We often forget the Asian side of history. Would this pistol be proper for a Waterloo or 1812 reinactor - no. But it WAS there for real in the the British Empire's Asian Realms in the late 18th or Early 19th century.
