68 bench seat ID

[usmcm1a]

I have a 68 malibu with a strange bench seat in it. It is blue cloth/ vinyl seat with a center arm rest and the seat back realse is located on the back. I am trying to figure out if this is an orgianl seat or an after thought. the fisher body code is 772-a-

Looks like a Olds front seat to me.
