I’m doing some research on A H Fox J-Grade Single Barrel Trap (SBT) guns, and I’m asking for your kind help with this survey.
Please look at the macro pictures included here, and compare with your gun(s). I’m mainly interested in Fox J Grade SBT guns, not Fox K, L, or M Grade guns.
First two pictures are of the engraving on the back end of the barrel breech. Does your J-Grade Fox look like A or B?


The second set of pics show the matting or stippling on the breech end of the barrel rib. Does your Fox J-Grade's rib look like C or D?

Please reply here, or by PM to me if you don't want to do a public post. Let me know if it's A or B, and if it's C or D, also your gun's serial number if you are OK with that. I will, of course, give credit to all contributors as this research goes forward. Thanks very much for your time. I really appreciate it.
Frank Silvers
