The entire production of the signature series Colts was done at Lou Imperato's factory but he was authorized by Colt to use the Colt name and distribute the guns as Colts. The may not have the same status on the collectors market as the second generation C & F models, just as the second generation models don't have the same status as the first generation models from the 1800's, but, in my opinion they are Colts. Read the following and you will see what I mean.
Here your info on 2nd Gen. Colts From The Blue Book Of Modern Blackpowder Arms.
COLT´S MANUFACTURING COMPANY, INC. Current firearms manufacturer with headquarters located in West Hartford, CT.
Colt´s Manufacturing Company, Inc. is the previous manufacturer of 2nd Generation Colt percussion revolvers located in Hartford, CT. Colt used subcontractors to supply rough castings for the manufacture of these black powder pistols. Throughout the production years 1971-1982, these rough castings were produced in Italy and the reproductions were completed in the United States. Initially, Val Forgett and Navy Arms provided these parts/components during 1971-73. Lou Imperato supplied these parts from 1974-76. In both instances, these revolvers were assembled and finished in Colt´s facilities in Connecticut. Finally, from 1978-1982, Colt subcontracted both parts procurement and final production to Lou Imperato and Iver Johnson Arms in Middlesex, NJ. Colt percussion revolvers produced by Iver Johnson had frames, center pins, nipples, and screws manufactured in the United States. In all instances, these revolvers were manufactured in accordance with Colt´s strict specifications and quality control. Additionally, Colt´s performed final inspection for all models. All percussion models manufactured from 1971 through 1982, either by Colt or its subcontractor, are regarded as authentic Colt pistols and not Italian replicas.
The Colt Custom Shop also produced a limited number of special editions through the early 1990s from 2nd Generation production inventory. (Colt 2nd Generation models in the white are still known to exist.)
And the Third Gen Info from the same source.
COLT BLACKPOWDER ARMS CO. Previous manufacturer and retailer of 3rd Generation Colt Black Powder pistols and muskets located in Brooklyn, NY 1994-2002.
All 3rd Generation Colt blackpowder models are also referred to as Signature Series Models.
A reprise of the original Colt Blackpowder line, along with historic models not offered in the 2nd Generation, and a new series of Commemoratives, each model (with the exception of the Heirloom Tiffany 1860 Army and 1842 Texas Paterson) bears the Sam Colt signature on the backstrap. These 3rd Generation models were manufactured under an authorized licensing agreement with Colt Firearms by Colt Blackpowder Arms Company ”“ the same company (and many of the same craftsmen) responsible for the 2nd Generation Colt revolvers. Although parts for the Signature Series were cast in Italy, they were fully assembled and hand finished in the United States using the proprietary Colt formulas for bluing and color case hardening.
Colt Blackpowder Arms Company Signature Series revolvers are regarded as authentic Colt pistols. The 3rd Generation models have original Colt markings, including the barrel address and serial number stampings. There are no foreign proof marks on these authentic Colt models.
