The choke is interesting! I have not measured it yet, but, it appears that the last 1/2 to 3/4" of the barrel has been swaged(?) down to form a choke. Many of these guns have rifle barrels that are bored out. Apparently, the threads were turned down to allow the rifle barrel to be turned in 1/2 turn more, putting the rear sight dovetail and screw hole under the forend. This gun does not have any rear sight mountings under the forend, such as I've seen in photos. There is, however, a piece dovetailed to the barrel to receive the forend screw. There is the possibility that this is an original rifle sight dovetail, or, it may be one of the guns that used an actual shotgun barrel. Very little info is out there about these guns. About all I know is that it is a No. 2.
