Colt Dragoon Identification

[Flintlock Fellow]

I picked up this Colt Dragoon this afternoon from a local gun store. Serial number is “1277C”, which I can’t seem to find in Colt’s serial number database. Backstrap appears to have an engraving of Samuel Colt’s signature. What do you think? Some sort of commemorative?

Never mind. I believe I’ve determined this to be a ‘Signature Series’ Dragoon made under license.
