I have my eye on a couple of .275 Rigbys and wanted some advice from those more knowledgeable about them than I am. They are both marked "Rigby .275 High Velocity" on the top of the receiver ring. Barrels have the marking of "John Rigby & Co - 43 Sackville St. London". No load regulation data that I could see. Both rifles are in very nice shape, all original with no refinishing, in makers hard cases. One has a SN in the 57XX range, the other one is in the 63XX range (SNs on the trigger guard). The later gun has a 25" barrel, bore looks perfect, with a three leaf express sight (one standing, two folding) and a hooded bead up front. The earlier gun has the same sights, a partial coverage leaf pattern engravings, a shorter barrel and claw mounts. What are reasonable prices for rifles like these? I have a couple of pictures of the later gun but can't post/host them.
