A bit OT but....
Rocketman, I know there are those that will question whether they are 'Best' guns but Blanch made their 'Best' baraction sidelocks in the early 1900's on a Webley screw grip action. They also generally had a through lump. Usually engraved by the Kell workshops and, to my eye, up there with the best but no doubt the purists will say it can not be a 'Best' gun with top extension, Screw Grip and Thru Lump.
Frankly I don't care, they are gorgeous guns and I would take one over a cookie cutter Purdey or post 1900 H&H any day.
Blanch engraved their 'Best' guns with the production year in Roman numerals on the trigger guard bow and all the above described guns carry that engraving.
