What are all the patent dates on that revolver?
Can you attach a photo of the gun?
The address line is one found on a Colt Model 1849 Pocket Revolver, but the serial number range should be from 187000-340000. Is there any chance there are two more digits in front of the "6396"? If there might be, take some chalk and rub over the area to bring out the marking. Let me know what you see.
The other problem is that the Model 1849 is chambered in .31 caliber, not .36. Are you sure it is a .36 caliber?
Ok - I believe what you have (based on a .36 caliber, with the serial number provided, the Colt address, and the photo) is a Colt Pocket Model of Navy Caliber revolver (Model 1862).
Your gun was made in 1862, and is an antique.
Let me know if you had any other questions on that gun.
Just checking to confirm you saw my answer above on your Colt.
