Well it’s different. Originally made with 2 1/2” chambers (1 1/8 oz proofs), but who knows now? It looks like a very basic Webley & Scott with the additional extra charge disk set strikers, single trigger and ejectors, using the very sturdy Webley & Brain lockup. This gun was designed for hard use and built to last for a long time. The stock appears to be maple, and while I suppose W&S could have had the gun modified before delivery it almost certainly was done in Canada or more likely the US. This gun has been extensively modified for competition, probably trap judging by the high comb. What I see that doesn’t look original……
Vent rib - just about unknown on an English gun of this vintage.
Maple? Stock - not normally used on English guns.
Monte Carlo butt stock - very rarely shows up on custom stocked English guns made for a very tall, long necked shooter ( like 6’6”). But never with that exaggerated tight grip, white spacers, and certainly with the adjustable recoil pad.
Extra long beavertail forend - an American invention.
Without being able to measure the stock it looks like a modest grade gun that has been modified and custom restocked for a very tall North American trapshooter. Pre 1960 and the popularity surge of over/under guns, side by sides were seen more commonly on North American trap fields than today. It may have been set up for International Trap or more likely Live Pigeon competition. Including the ventilated rib and possibly a custom trigger these modifications represent a considerable investment, it must have been worth it to somebody although general lack of wear suggests little actual use. Value??? Welllll……
As an original basic Webley & Scott field gun in Very Good original condition in our currently depressed market, it would be hard to get $1000. But if it’s been rechambered to 2 3/4” with no reproof that goes down. Bore condition?? Lockup?? Trigger operation?? Ejector operation?? Most people won’t pay a premium for a modified gun because like a custom car it doesn’t meet THEIR vision, best values always follows best ORIGINAL condition. And yes, there are a very few very high grade Webley and Scott guns out there that can sometimes bring a premium price but this isn’t one of them.
