The 2nd Generation Colts (also called "black box" Colts) are Colt Firearms' remanufacture of their old C&B revolvers. Serial numbers for the 2nd gen models picked up where the originals left off. I have a 3rd model Dragoon & it is well finished & shoots fairly accurately with conicals. One of my favorite pieces. They are semi-collector pieces and demand a higher price than other repros.
The Signature series, or 3rd generation, have a facsimilie of Sam Colt's signature on the backstrap. Have a Walker & 1851 in that series. The finishing of the revolvers are good, but have many rounded corners. Also have their 1861 Special Musket, which had many flaws. I had to send it back to Colt w/ a list of discrepancies, including no half cock notch cut in the tumbler! :shocked2: Barrel is great however, and once I worked on it it shoots very well. But why should I work on a $700 rifle? Coulda got a Traditions 1863 that looks as good for 2/3 the cost.
The parts were made in Italy, right now don't recall who did it, & assembled by Colt in the US. THus they could avoid the "Made in Wherever" stamps. I think they used new trainees for the polishing of the Signature series: well polished but looked like they leaned into the buffing wheels, rounding corners and screw holes.
They are great for reenactors who go to great lengths to "defarb" everything, as the stampings are exactly the same as the originals. As for shooters, I think some of the Italian imports are just as good & a lot cheaper.
