The torched hole is the lever that operates the pump. The round knob is the release valve. The three handled lever appears to operate the square shank and C shaped piece that extend down alongside the ram. Probably some kind of manual raising mechanism for the ram. I think this was not made originally as a general purpose press, but was modified into what it is. Probably manufactured originally for some specialized purpose. Note the lack of holes in the legs of the press. How about a close up of the data plate.
