can anybody id these bucket seats

i took these out of an early 70's duster back in the 80's which had a factory console in it. i was told they were rare factory seats(which they may not even mopar at all). they were bolted in the factory holes in the car. from what i've read these deffinately are not early 70's seats at all. these are the only pictures i have of them. they recline and have no plastic backs,there is a zipper up the center of the back. any idea what they are from would be great,thanks
