Multiple simultaneous drill fixture.  An educated guess . . . Fixture appears to locate off the countershaft hole and the plate guides the drills (or taps also?) for the transmission top threaded holes (1/4-20 uss thread)  Drills them all at the same time, same distance, same depth.  You wonder what happened to all those unique machines the factory utilized for years and years???  Probably broken down and sold for scrap.
