Gunnie ,I sent you an email.
BTW ,which gunsmithing books have good info on the BSA Martinis? I wouldnt mind having a look.
Also ,mine is a 22 Hornet and the barrel has another stepped up portion about 4" in front of the barrel tenon for the scope bases to mount on and to locate the forend wood. It also has the flip up peep site and Sportco stamped on the barrel. What model would this one be ,just a standard one or what?
