I was looking at a gun today that I was told had 3 inch chambers and had a serial number 1612, and I understood the PIN guns were Sterlingworths, so my questions are; how did it get that serial number, and why would a PIN gun have a 3 inch chamber? I going to try and post a picture. The gun is marked just FOX where Sterlingworth typically is. Thank you.
