I would like to help but I need a bit more info, Most of the TC guns have a model stamped in the barrel, such as Hawken, Renegade, New Englander, Cherokee, Seneca just to name a few. If not, there were some models of the same guns produced without the TC model stamped. A detailed description and caliber would help me to identify it and give you more info on it.

Thompson Center does not publish date ranges for there guns, but from the number I would estimate the date to be mid 90's
