Interesting story on Stanbury's Webley & Scott, Ted. The article mentions that the gun was out of proof when the current owner bought it. I wonder why? Not because of bore diameter. Could it have had original 2 1/2" chambers, later lengthened to 2 3/4" without reproof? 2 1/2" chambers and 1 1/4 oz proof would be very unusual. And the gun was made in 1921, but chamber length wasn't a required proofmark until 1925.
