No hammers on this one Londonshooter and Pinfire, but I think you will like it anyway.
Westley Richards Best Quality 12 gauge cased two barrel set with deluxe checkering, fancy back shaped action, WR patent triple bite action, ejectors, 'one trigger' and hand detachable locks. Made in 1924 with 30" barrels, a second set of 28" barrels was added by Westley Richards in 1934 and were subsequently rechambered to 2 3/4" and fitted with Briley thin wall choke tubes. The bores in both sets remain pristine and in original proof dimensions. The beautiful custom case by Jekyll and Hide, London, New York, Paris and Johanisburgh was likely added at this time. The gun was the long time possession of J Harold Crang, a Toronto financier and Holstein cattle breeder. In 1956 Mr Crang broke 1000 clays in 47 minutes and 53 seconds, a verified record that still stands today. He used three guns and had two loaders serving him and stopped only once about half way through for a glass of champagne! Sounds like my kind of guy. It is not known if this was one of the guns used.
