Any thoughts on this? Fuzzy quarter for scale. Mechanical aviation relay. Can pop it open if you want.

I've got a load of stuff I'm processing through at the moment which includes lots of odd things like this amongst a ton of boards from avionics stuff.

Gold ends might be a possibility but I'm thinking this probably is in the heavier end of what normally goes in that. If you have quite a few you might pop one open but keep them separate and email Chris (Boardsort email) with a link to this post so he can let you know exactly.
