I picked this up for a few bucks at a garage sale. Aluminum.
Since there is no windmill thread, may I ask if this could be aviation-related?

I think it's from an agricultural or commercial fan or blower unit. Putting "P1146" into Google search came up with this website as the top answer:- https://www.canarm.com/hvac/
There is a big range of ventilation, circulation, air movement products in there but they are classified according to whether you have pigs, cows, wall units, roof units: not by part number.
but P1146 must be in there somewhere, maybe in the spare parts lists, which are classified as 30 series, 40 series....90 series, etc. Not helpful to us but I am sure this fan, or it's CFRP current replacement is in there somewhere. If you have the patience of the people who translated Linear-B https://www.classics.cam.ac.uk/sites/default/files/process.pdf then go search for it.
