Impossible to answer without a detailed description of all markings, features, and who made it.
No such model exists.
The only way you might find out is to get a letter from Colt. It MIGHT show that it was sent to an individual.
If it's a 1863 model then it would be a cap and ball model, not cartridge, and it would be about a 31 or 36 caliber. However, if the piece was converted to cartridge then it COULD be a 32 cal. cartridge.
