First class work in every way. I MUCH prefer them to Briley's for the same work. They also do the best job of forcing cone lengthening I have seen on clays guns, they cut a long cone and polish it out so well it disappears when you look for it. Your Spanish boxlock might benefit from that also. Their final polish work is better than any I have seen, at least on the several clays guns they have worked on for me. My guns go to Florida for such work, not Texas.
