Mr. Chambers
I believe you took Mr. Petrovs statement out of context.I believe he was very clear that he was talking about Kornbrath the engraver and not as a gunmaker.I do know that Wilson had quite a file of Kornbrath's personel papers.I have been reading about Kornbrath for over 40 years and have never heard anyone call him a gunmaker.Perhaps it was possible that he could assemble a collection of parts to make a gun and then engrave it,parts that someone else had made.I don't believe that would qualify him as the maker,perhaps the finisher.This is becoming tedious,splitting hairs as it were.
