Lagopus, you are correct that it is Joseph Asbury.I had often wondered on the correct name/spelling so called Robin at AA Brown & Sons Alvechurch.However no-one home ( what was I thinking 3pm Christmas eve)Any way I went to the web site of A.A.Brown & Sons Alvechurch knowing that they owned the name and machinery associated with J.A. There the company name is given as Joseph Asbury. I recommend anyone interested in a review of a family run gunmaking business in Birmingham to visit the website and check out :The Firm,
Regarding the engraver I must defer to Roy H on this, I believe he is right in identifying it as the work of Harry Morris.Geoffrey Boothroyd knew Morris well and wrote of him in one of his books, unfortunately I can't reference it at the moment and must away to do some Christmas shopping for the the Missus or I'll be in the doghouse,not a pleasant prospect.
With that I'll leave and wish all of you a Fine festive season.
All the best
