Re: Stub twist gun question Archived Message Posted by Tom Garver on December 26, 2016, 1:04 pm, in reply to "Stub twist gun question" Marcus, your gun was manufactured sometime between 1885-87. The F quality was the lowest grade at that time. There are no remaining records for this era so hopefully David Williamson will chime in here with a closer estimate of the manufacture year Message Thread: Stub twist gun question - Marcus December 26, 2016, 12:35 pm Re: Stub twist gun question - Tom Garver December 26, 2016, 1:04 pm   Searching
