Just to add a bit more. Asbury was working for Joseph Curry, a Gunmaker to the Trade just off Whittall Street in Birmingham so a good chance it started off life in Curry's workshop.

Dan, sadly a lot of the information on barrel marks has been lost in time with old Gunmakers and Gunsmiths going to a different 'workshop'. I was told a few by an Oldtimer. Such a source of comprehensive information would be a treasure indeed. Lagopus.....
