You are bidding on an early plow plane.  The plane is mainly wood. It has a metal blade that appears to me as being forged metal. A metal screw top center adjusts to the desired depth of cut. The plane adjusts in width by two wood pegs that the cutter can slide on. There are set screws that hold the width in place. One of the screws is missing and the screw that is there tightens but then slips. One of the wood peg slides has been broken and it has been glued. I could not find any markings. I would guess this plane is pre 1870, It has a nice feel. It is 9 and 1/4 inches long. It is in good condition with the defects noted. I combine shipping on multiple purchases.
