I repro the drag rope (made from components just like in the M1 gun manual (last pages) See picture $68 US + ship....or pick up at MVPA National from Rod Shaver's booth (Scout Car Rod)....I have four rectangularly spaced bolt holes on lower left shield - looks like it matches the holes on the "lube order or records holder" on your right shield (backside)...also have four hopes on upper left shield - no idea what goes there. Ideas?
