Joe, let me know if you need any further assistance. I find that I have no useful research material on Birmingham guns. Nigel Brown, I think, is the author of a book on Birmingham guns which is a companion to his book on London guns. His book on London guns (which I do own)includes information on the recent owners of the records of gun companies and I assume the Birmingham book has similar information. Boothroyd indicates that he was able to obtain old Cashmore catalog copies from Gunnerman Books. These reprints may still be available. Murphy
