By interesting coincidence, I have a friend in the process of making up one similar to that right now. He's fond of the unfluted cylinder, but other than that, his gun will be a dead-ringer for yours.
Well, I sort of got disconnected from this forum, and recents attempt to log on went thwarted. Never could seem to get my user name and password just right. Finally got things together and got logged on after some wiggling around.
And after getting back in, thought I was forgotten so figured I was a new member. Anyway, here I am.
