I have a couple… I think!
Number one would be my 1851 Navy Richards mason conversion. Was told by the good folks at USFA, that "less than 35" were ever produced. A product of the late 1990's, it is, obviously, an all Italian (Uberti) parts gun that is beautifully finished. Serial number is 2048. I had a presentation case made for it by
www.billscases.com. It has never been fired and I keep it as an example of the transition period between cap-and-ball and cartridge.
Number two - and this one is "iffy" - would be my matte nickel (Rodeo II) finished Double Eagle, serial number 73150, that was ordered from USFA right toward the end of their SAA production. Gun was originally ordered with the bright nickel finish but when it came in it had the Rodeo II matte finish. Was told by Gary Granger, here on this board, that he was unaware of any Double Eagles with that finish. Later I saw another, just like it, for sale on GunBroker. Lord only knows how many DE's left the factory in satin nickel. I can only hope that there weren't too many!
