Coffinmaker's "memory of a gnat?" Then count me in as well! I remeber it as he has stated.
The USFA China Camp model was one of the first "specialty guns" that was introduced well before 2002, the accepted date when USFA was legitimately able to make the "All US Made" claim.
Named after the late champion CASS shooter, Dennis "China Camp" Ming, it was, as stated by USFA, made to his specifications and was "regulated to point of aim" (again, according to USFA).
As for the finish, there was a bit of subtle deception on the part of USFA. They called it their "Silver Steel Finish," touting it and so vaguely describing it that one was left with the impression that it held near stainless qualities. It was nothing more than highly polished carbon steel, the same steel used in all of their/Uberti's, products at the time.
So... to directly respond to your concerns, YES, your China Camp model is, with a 99.9% probability, made up entirely of Italian/Uberti parts.
Is that a bad thing? Even before USFA went to "All US Made" they were doing an exceptional job of assembling & hand
fitting/finishing imported parts. Pre "All US Made" guns (with the exception of the some of their very early USPFA's - and that is another story) were fit & finished here to a higher standard than those seen from Uberti or others.
So...What do you have? A very interesting piece if USFA history! I wouldn't hesitate to buy one for my own USFA collection.
