The same Beesley. Beesley seems to have made a number of guns on his own design, which patent he sold to Purdey's for sufficient cash to get himself in business. He also supplied guns of differing design and lower quality grade, guns I believe that had origins in Birmingham. There is not definitive information as to which or to what extent Birmingham origin guns may have been finished in Beesley's shop in London. The self-opener "Beesley" action was his shop's best gun and likely made mostly in his shop.
