I just took over as my police agencies armorer and found something in our armory that I need help with. I do not need the fact that it is not legal to own and so forth just help with ID. I have researched a few findings about the only company name Deeley & Edge located on the shotgun. I believe it to be 10gauge. Now for the visible markings. On both sides of the action just below the breach it has W.B. DANBY.( Internet search, resulted in a hunter from the early 20th century) On the top rib between the barrels is THE SPECIAL CLUB GUN. No findings via internet on this. Next is the forearm release latch. One side PATENT, the other DEELEY & EDGE. Finally several markings on the underside of the barrels. Both barrels marked with some type of proofing (crossed arms type) and 12. Then on one barrel, 11B NOT FOR BALL. Last is a set of numbers between, 8105, possible serial. This shotgun was in a box way in the back it appears someone did not care for the beauty. The barrels were cut off and the stock is broke. Any help would be much appreciated.
