Help radiator. I know what it isn't.

[signsup]

Got back from radiator shop this morning after having it deep cleaned after eBay purchase. Represented as 42/48 Ford radiator. When I took out the Bubba aluminum radiator and it had mounting legs at the bottom and special slots on the upper sides for carriage bolts and straps to the inner fender, I knew that this radiator was not apples and apples.
So, now that I have a eBay purchased, but professionally cleaned and ready to run radiator, it would be nice to know exactly what car this radiator would fit.
It is marked 21T/JA but that might be the type of construction, not a model number. No other names or numbers. Feels like mounting points along the side as well as an additional strap up each side with smaller holes that I presume would mount some sort of shroud.


Fingers crossed that it is for an earlier Ford and we can find a good home for it. But, any help appreciated. Looks like I get to paint and reinstall the Bubba radiator. It really doesn't look that different. Thanks in advance.
