I would recommend looking around the gun for any sort of markings, specifically around the barrel and yoke, which is under the cylinder. Most guns have markings on them to identify what and where they were manufactured. If you do find a serial number, then you may be able to do a serial number search on it. However, your firearm is old enough that it is not legally required to have any markings.

Be careful not to shoot the gun while inspecting it and to point the muzzle in a safe direction. If you are unable to find any markings, visiting a gunsmith would like be required.
