I had a Westley Richards single barrel trap gun. Really a nice gun to shoot. It was made in 1908 so looks like it was made in the first year of production. The receiver was case coloured with only a modest amount of engraving. It had a 32" full choke vent rib barrel. Stock dimensions were comparable to current trap guns. It was a bit light at 7 lb 9 oz but with 1 oz loads recoil was modest.
From time to time I see one for sale but not too often.
A friend now is the proud owner and he shoots it regularly.
