I have three 2” guns made by Arthur Howell in Birmingham, and all are marked “JA” under the barrels. One was retailed by W. Hodgson, Ripon, one by Henry Monk, Chester, and the 3rd by R. Robinson, Hull.

It is my understanding that those machined barreled actions were sourced from Joseph Asbury, sometime before Asbury’s equipment was purchased by A.A. Brown.
