Gents, I lost my cocking tool (no smart-ass comments, please). looked on the Internet and frankly don't trust what I see. It is for a 410-field grade double, beautifully refinished and reconditioned by Griffith and Howe, up the pike from me in NJ. I vaguely remember from an ancient thread on this board that one can use a particular size box wrench to do the job. That might work, but I would rather get something more amenable to this purpose. Any suggestions from a reliable provider would be appreciated.
