Other than the rather large 75-caliber [that's a lot of lead per shot!], there's nothing wrong with those from India. Yes, they use heavy. clunky teak wood instead of English walnut (if buying a caliver) or wood from a fruit tree, e.g., cherry, but old/early BP arms tended to be somewhat 'clunky' in design and execution anyway, LOL. And of course it is scoured far TOO bright in polishing ... holy cow, you'lll need sunglasses!
But for safety of the barrel whilst shooting; no issues IMHO. I have proofed one myself, a 75 - for my own sanity - using a double-ball/heavier charge than it would ever, ever see in its lifetime and there were no changes in the barrel dimemsions as measured to the 10/1000s of an inch, in spots from the breech and down (up?) the barrel in 1" increments.
I've since upgraded to one built by Brian Anderson, who unfortunately just retired, and yet the 'import repro' was just as fast and reliable in its ignition. You do hit on a sore spot for a need in the BP community ...
Now to me, that matchlock from Lodgewood is a tad over-priced for what it is, or for what one would have received (even caliber) if Brian had made you one, however ... beggars can't be choosers, however ... also admittedly, BP market prices are indeed UP all over! Now I do know of the builder Steve Krolick, and have other BP arms he has built, and they are built very, very well. Note the description says it is a snapping matchlck, but it isn't - you pull the 'tiller' or bottom lever leg of the serpentine to fire it.
