All originals were made as three band, the whole two band artillery model is sort of a made up deal. Colt sold the Colt repros, Chattahoochie sold the Amoskeag and LG&Y repros.I have a Colt Signature Series M1861 Special repro and the OP's gun is not the same as mine. Several notable differences: mine is three-band (w/ longer barrel as appropriate), there's a Sam Colt signalture engraved on the trigger guard, and there's "STEEL" stamped on the barrel under the proof marks.
