Name that Box Blade?

I just picked up this 60" box blade today off Craigslist for 75.00. There are no markings on it and I'm trying to determine what mfg this is made by so I can order the 3 point hitch pieces that are missing. Poking around the only thing that I can find that mine resembles is a Buhler Farm King Y60BS.
Looking for someone to chime in and see if this resembles anything in their collection. Any help would be appreciated.
