I'm hoping someone can tell me what this is. It is a large double-action revolver. It looks kind of like the early Webleys, but the barrel is round, not slab-sided. It has a rather complicated crane, AND it has a thumb safety! Unlike the one found on the Webley-Fosberry, it is pivots at the back end like modern thumb safeties. It seems to be fully functional. It is almost completely patina'd, but is otherwise in very good condition. There is a groove in the sideplate from the movement of the safety. It is about .44 caliber (I have not measured it.) There are no markings of any kind anywhere on the gun. A value would be great, but at this point I'd settle for finding out what it is! Thanks!
