There are many different models that were produced in .36 caliber so you will have to narrow it down some. try here after doing that. http://proofhouse.com/colt/
It would be in 36 caliber or 44 caliber...
100 to multiple thousands of USD depending on EXACT configuration, condition, finish, box, accessories, history, etc.. any chance it's a 44 cal. cap and ball
Yes. The Navy model of 1851 was in .36 caliber.

Impossible to answer without a detailed description of all markings, features, and who made it.
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.
No such model exists.
