If you have contact with them, please ask them if they sold their wares to Veteran Arms, out of Georgia. Also ask them if they shipped items to the US without any touch hole drilled.
But I have what appears to be an identical Blunderbuss, from VA and it's awesome! Try getting a blunderbuss kit and have it built for anywhere south of $2K. The wood (teak) is what the wood is, but on mine, the stock is nicely proportioned and not clunky, the barrel appears well machined (and I proofed it), and the lock works so well that most people wouldn't have to touch them. Me? I tune ANY lock I get from anybody, even a lock frm Chambers or Kibler.
