Greetings All,
As for if, or if not, this gun was made up from Uberti parts (along with another Italian manufacturer - who's name escapes me at the moment), I can, with absolute certainty, guarantee you that it is an entirely Italian made gun that was "fit & finished" by USFA.
As for USPFA vs. USFA markings, that is also no guarantee of the gun's heredity. Hundreds of Italian import guns were marked USFA. USFA markings alone do not make your gun an "all made in the USA" firearm. The line didn't change with the change of the name. USFA continued to import Italian parts, either entirely or in part, long after they removed the word "Patent" (as the result of threatened litigation from Colt Firearms) from their name.
All that being said, the USPFA & the USFA C&B's, along with the handful of cartridge conversion revolvers, were, unlike the pistol represented above, beautifully fit & finished with vivid CCH & bluing. God only knows what happened to that gun!
I am the proud owner of one of less than 35 1851 Navy .38 cartridge conversions that were issued by USFA (and it is marked as such, not USPFA). Yes, it is entirely Italian made but, having been assembled & finished by USFA, stands head & shoulders above any Italian import that you will ever find.
