Can anyone identify the maker and purpose of this prop. It's about 60" from tip to tip. I presume it's for testing engines but can't find anything on the drawing number in order to date it etc.

The only stamped details are DIA 91411 DRG WF 490

It certainly looks like a test club. You might check to see if the hub dimensions match any of the common engines.

Hi and thanks for your quick response.
I can't get the link to work ('404 error message'). That's not the main problem though. I can't measure the propeller either as I don't currently have access to it.
I was intrigued by the 'W.F.' and wondered if that meant anything to anyone?
