Would anyone know what this is?

Looks like some kind of measuring device that might fit down inside an aircraft engine cylinder.

Thanks.

Could it be for setting props?
 
Elliot - that is a brilliant idea. What do you suppose the large and small holes are, at the bottom of the "piston"? Also, the small threaded hole a few inches above the bottom?

Honestly I have no idea. The tool just looks (to me) to be used to balance a prop.
As for the threaded holes, that is above my pay grade :smile:

Rick - do you happen to have any original photos of the WW2 P&W shop(s) where your Dad worked?

I'm afraid not, Tom. I have a number of his engine repair manuals, some P&W pins and his ID badge. He always told the story that on the day I was born he was trapped in an engine testing room when they turned on the engines and only got out by signaling with his flashlight.
