Mark:
I agree the number may be a serial number not patent (even though it says "Patent No.") but it also says on the top strap "J. Adams. London" and is of the wedge-frame style. I understand Adams contracted out to other companies to make wedge-frame reovlvers with the Adams' name. So would this mean that Webley made this piece? How can I verify this? Is there a list of serial numbers somewhere?
