I have researched hours. The gun is in good condition, barrel looks excellent, stock needs replacing which I can do (jack of all trades, master of none). My problem is IDing model & year of manufacture. SN: 713118, stamped on the barrel & behind trigger guard. 410 G in diamond stamped. Stock end is stamped "118" & metal part of fore-end "118". Under the barrel between the fore-end latch & rear of barrel is stamped "DDH". Top of barrel "Genuine Armory Steel", left side - " Crescent Fire Arms Co, Norwich, Conn. Above this appears to read "Direct Ejector". From pictures I have seen on the web, mine appears to look like the "New Victor Special". Rebounding hammer, Fore-end over sized, knob pistol grip, not walnut wood. Measuring the depth of the chamber to the cut shoulder inside is 3.26". I have fired 2 3/4" shells in it in the past & would never go above that. It was my father's, I am 73, retired US Army now rancher in Central Texas. It is kind of a keep sake, but I would like to shoot it. Numrich has some parts for the "Victor", flat springs, I would get just for spares. Any info would be nice, I have read the history of Crescent. Did the firing pin have a return coil spring? Also, what are the steps to disassemble the the receiver? Thanks, Herb
