Propeller Identification help!

I received a propeller that I cannot identify via internet research...
It is a US Propeller model 22008 serial number 00642. I have also located the USP with the number three within a cirlce stamp on one side. I was hoping that you would be able to tell me more about. Any information that you are able to locate and share will be very much appreciated. Thank You

U.S. Propeller of Los Angeles made both drone props and certificated aircraft props. Unfortunately, to my knowledge none of their manufacturing records survive today.

I recognize that drawing number and as Lamar says, it's a UAV prop. They must have disposed of thousands of that model as surplus, because they are very common.
