PK blade for earlier models. 60's to 73 I'm told. Clamps on the frame in front, hangs off straps in back. Super heavy, must be 1/4" thick blade. Has one spring missing, and a small strap that mounts same springs. There is a pix from manual in PK forums here. Won't ship, must pick-up. I'm in Huntington, IN 46750 private message here. Asking $125
