I found this part thing at Luke AFB Aux 4 airfield.
It measured about 1 foot, it was heavy with a steel coil spring inside the cylinder, & steel rod sticking out. no part numbers.
What is it?
Note many F-84s crashed nearby.

Could it be a trim jack screw for rudder, elevator, or aileron? Something like that?
I don't know what the loaded compression spring would be for (artificial feel?).

What's on the other end of it?

Thought it could be airfield trash but it looks like it took a hard hit! Surprised there's no p/ns.

I'm thinking it is most likely from a tow target. It is too heavy to be from an aircraft. 
however, a few early jet aircraft parts were found next to it, but then again, early jet aircraft parts are found all over Luke Aux 4.

Interesting find.  The coarse threads make me think "non aircraft".  Definitely a damper or shock absorbing device of some kind.  The pawl on the one side (must be a slot where it is mounted?).   Orientation of the pawl indicates it might be for locking the spring in the compressed position?  That's an awfully heavy looking spring.  Aluminum casing? (it isn't rusty).  Smaller mounting hardware - is it AN or coarse thread?
Kind of reminds me of my older "mechanic days" when a guy would disassemble something for the first time and we'd go "add" an extra part or two for when he'd try to put it back together.   Dennis

How about a spring dampener for the tow target assembly?  To reduce pogoing between tow aircraft and tow target.  Things like that didn't have to be aero lite or aircraft quality built/manufactured.  I've seen similar simpler dampeners on small tow trailers.  Something like that could be obtained and maintained locally.
