Hi gents, just found a second gen 1860 army with a 5&1/2" barrel with the serial number of X002 on all parts, including the pin and wedge. Fine oil finished walnut grips, blue and casecolor, FLUTED cylinder, 99.8%, unfired. I called the factory but no info although they said the X serial numbers are usually guns that were prototypes, SOOOOO, I have this prototype for sale if anyone is interested and will send photos to your email. No box came with it, from a 40 year old collection, and I suspect it was "liberated' from the factory during the bankruptcy where many things walked. Call me at 330-952-0031 or email at [email protected].
