Technical Need help figuring out what this XL door is for?

We picked up a model T and quite a few parts this door was in the parts, what could it be from?

 

Fisher bodied car, '25 - '26 era

 

I once had a 28 Chevy that had that belt line.

 

That door looks like the extra door in the "Studebaker vs Gardner, I just don't know" string... check it out

 

I was wondering maybe a Cadillac?

 

Looks like the door on pops 27 Chrysler business coupe.
