US Propeller Inc. 22008 Ser# 413C

[tomsno]

I have a wooden propeller made by U S Propeller Inc with the number 22008 and ser# 413C on it. It has a 3 bolt hole pattern with a 1 7/8" center bore and red tips. It measures 39" overall length. Can anyone tell me about this propeller as to where and when it might have been used. Thanks

It's a UAV (drone) propeller. That model turns up frequently. See this page for some examples of similar props.

I assume it is from WWII, is that correct?

Yes, I think so. They must have been way overproduced and sold off as surplus, because they are often found on eBay and other places for sale.

It's a drone propeller. I think they were for target drones. See the link in one of the posts above.
