I'm looking for a shootable set of 12 gauge Parker Lifter barrels with the square corner from an early lifter. The ones I'm trying to replace are not marked in regards to frame size but I believe these would be equivalent to a #1 frame. The hammer pins are 1 1/16" apart. Let me know if you might have a set leaning up in the closet. I'm not fussy about length, or condition as long as there is enough MWT to be able to shoot them.
