Found this blade on CL near me, just wanting the 54" moldboard to put on my 520H, anyways bought it and already swapped moldboard it will need a new wear edge (got that covered) and the original tabs for the round skid shoes were removed sometime in its previous life (have a fix for that too), but since I can't find an ID tag I was wondering if anyone would have a clue to what it originally would have been made for , also seems to be a lot of custom parts added along the way as well as the angle handle and axle bracket, P.O. said he had it mounted to a C161 manual lift ? , Thanks Jeff.
