Miller is correct about choke being a required marking on the L barrel if it originally had at least .008 constriction. (The maker could have requested it to be marked Choke with as little as .004 constriction.) The right barrel, however, is a strange case. Not marked choke, yet it still has .007 constriction, and not jug choked. That would indicate to me that the barrels can't have been shortened very much. Shortening from 28", for example, would almost certainly have removed some choke . . . which means the R barrel would have started with at least .008 (and probably more) and should have been marked Choke. Possible they were originally 27" and only shortened 1/4"? Maybe a bad dent right at the muzzle, and not enough removed to have taken out any choke in the R barrel? That one's a mystery to me, if indeed the barrels were cut. One could, of course, request whatever barrel length one wanted. But pretty unusual to find a Brit double that doesn't measure to an exact inch. As noted above, other than guns with 25" barrels, it isn't even all that common to find them measuring to an odd inch, like 27 or 29. But there are clearly examples of those.
