This is my first attempt at posting a question. If I get any replies I hope I can find them?! I purchased a Sterlingworth around 43 years in south Alabama. It is stamped "The Sterlingworth Company, Philadephia Pa, USA". It is not marked "Fox Sterlingworth" as most Sterlingworths I've seen. It is a very tight, long barreled 12 ga. Serial # 51852. I assume it was a "transition gun" made before or after Fox made the guns, but I've never really known its origin. Can anyone tell me the history and estimated value of this gun?
