Thanks Everyone for the help

 

Part of the story,,,,, https://www.jalopyjournal.com/?p=21634

 

Stanchions...much early repro stuff up into early '60's was cast aluminum. Those are '26-7 roadster lowers grafted to the hinge cup from something '30-32.

 

Bruce look at those lowers again,,I say they are Model A

 

Yeah...not flat enough for '27! Remember all the cast aluminum stuff in the catalogs before they tooled up for more serious attempts at replacement parts?

 

25 t?

 

The car was built in 1949-1950....

 

Could be some "Orphan" Model roadster stanchions...has anyone seen one of these?
Still trying to ID them
