M2 reproduction armor. This piece is for the rear wall and would be the large lower plate. The holes that are used to bolt the rear steps to were accidentally countersunk. It really doesn’t affect anything because when you bolt on the steps it covers up the countersinking. It’s rusty but not heavily pitted so a sandblasting will clean it up nicely.
Because of the rust and the holes I’m only asking $50.
