Hot Rods Thoughts on what this trunk fits????

Bought this trunk last week and was wondering if anyone knows what it fits. (first 4 pics are the same trunk)
Dimensions:
Its about 38 1/2 in length x 14 in wide and 18 in high
The guy had other 1921 Cadillac parts.. I also bought a 1957 ford rear end for my model A roadster build, and these cool windows (last picture)
Thanks Rick!

 

Dang. Trying to remember which car . The curved back narrows it down.

 

That's an aftermarket add on for an early 30's sedan. Sold for many different brand of cars, and the only difference is the short side fins that take up the gap. You might get lucky and somebody will recognize the slope of a particular brand and year of sedan, but truth be told they all kinda look the same.

A well known similar brand of trunk was Potter, but I have no idea of the maker of your trunk.

 

thanks that works for me , it was just part of a package deal , but i did not want to leave it , tks rick
