Yes indeed, those Unison seats are "Very Rare". Only came in '54/'55 1st series Chevrolet trucks. I have two of them left. Recently sold one, for $800. I have one that has been re-upolstered, that I plan to put in my '53 Chevy COE. I might put the unrestored Unison seat(that is presently, in my COE) in my '51 Chevy pickup, if I don't sell it first.
