Technical Parts Identification Help Request.

I'm looking to re-home this back seat I obtained with an unrelated car. Somebody, somewhere needs this one, and I don't want to waste it by throwing it away. Does anyone recognize the shape, the pattern? The cover is real leather (not vinyl), and the springs in the seat frame are individually wrapped in cloth, similar to very old mattresses. I'm guessing this is probably early 50s vintage, but don't know what car. The driver's side interior panel is also included, if it helps. I can provide more photos, if necessary. Do these look familiar to anybody?



Thanks for looking.

 

Are you up for a wild guess? I'm leaning towards a late 40' early fifties convert. Buick, Olds or ???

 

Thank you, Tim. I'm guessing since they're leather, they might be Cadillac. I've posted over on one of the Cadillac/LaSalle sites to see if anyone over there recognizes them.

 

Most GM converts of the 50's & 60's had leather seats.
