I have an 1877 W&C Scott Premier Quality 12ga with Briley chokes. It was purchased, presumably in the UK by Chuck Webb of Briley who possibly is responsible for both the proofing and the chokes.

I broke a hammer and Briley Tig welded the hammer. The repair is invisible.

I have used it for sporting clays and it helped me into AA class.

I say choke tubes have made this gun more useful
