I have a parkerized Polish PMKMS Underfolder kit in EXCELLENT condition for sale. All of the numbers match except the bayonet. They bayonet and scabbard numbers do match each other, though. It is excellent cosmetic condition (most of the wear is on the underfolding stock). It appears to have been fired very little judging by the carrier and condition of the bore. The bore is crisp and bright. Price is $250 shipped. I hand-picked this kit from Greentimber back in the summer when he was at a Memphis gunshow - his kits were by far some of the nicest I've seen.
EDIT: I Found the rear trunion finally. Although not pictured, I have the original Polish underfolding rear trunion and it is included with the kit.SOLD PENDING FUNDS
