The original Cold Navy was definitely .36 cal. Many reproductions are out there and some are excellent. Also, some are in .44 cal. Beware of reproductions. It would be rare to have a cylinder from an original Navy in which the engraving is "just about perfect." Hope yours is original. Good luck.
Here are a couple of photos of an 1851 Colt Navy. Unfortunately, it's an excellent reproduction rather than an original.
