Very interesting 8-Bore. I have never heard the term you used- "Knick" rib. My 1940's era Pigeon Grade Trap has the so-called "Old Milled Rib" and as that is the only one of my 7 M12's with a ventilated rib, I have nothing to compare it to in the WRA lineup. Could you possibly "splain'"" a bit here. I traded off the the Rem 31TC 12 bore years ago, most likely against an L.C. Smith, who knew?? WRA started to "bite the dust" in 1964-- looks like Remington-UMC, except for ammo, is closing out gun production. Do they still own the rights to the Parker tradename, going back to 1934?? RWTF
