The Superior 54XL was Superior's answer to the M-M Criterion. Like the Criterion, the 54XL had wall cabinets and blank (non-window) sides. It's not "someone's attempt", it was a Superior model that they built.it would appear to be someones attempt to make a criterion type rig out of 54XL
but no I have not seen it or one like it before
Here are two photos of my 1975 54XL in it's "previous" life. Anyone have any clues on its history? Thanks. Jim
