Incredibly, I have this same exact fan. Bought it at Chickasha Pre-War Swap meet in 2023. I thought it was unique and bought it for a wall hanger.
The individual I brought it from said his dad owned several old cars and parts of this era in Oklahoma. He didn't know what it was off of nor do I. Would be interesting to know which make it is for.
When I saw your pictures, I thought wow, I think I have a fan assembly exactly like that and that number seems familiar. Thanks for posting.
