TC guns don't have a model number printed on the gun per say, they have a model name (ie Hawken Renegade Triumph Tree Hawk etc.) There is a corresponding model number in the catalog 9503 is the Hawken caplock for instance, but if you need to identify your gun go to the online auctions like gunbroker or auction arms and compare your gun to the photos there.
It's a 54 caliber round ball
