Thanks CaptCurl, I see the purdey bolt in the picture! This is the first time I've come in contact with this feature! I have a jones lever 58Cal/20 ga cape gun that looks almost exactly like this one! It is also unusual in that the splinter forend is permently hinged to the action, and the barrel set is removed by opening the action, then releasing the forend Deeley lever, which releases the barrels from the forend iron! This also is the only example of this feature I've ever seen!
