Help me identify a vintage electric component
ball:
Hello. I found this odd vintage electric component in the middle of nowhere (on a mountain). It has two wire-wrap-like posts connected to six thick metal plates which are soldered/welded together by hand. There is matting between the plates of unknown fibrous material and it's housed in a clear green plastic shell that was clearly never sealed.
I thought at first maybe it was some weird custom battey but it isn't sealed. Then maybe a ballast resistor but then it's housed in plastic. What could it be? A sensor?
bob91343:
A home made capacitor maybe.
MK14:
It does look a bit like the internal bit, inside an electro-magnetic door lock. I.e. The internal 2 wire coil assembly part.

What are the plates made out of? I would guess either battery of some sort or a moisture sensor.
Gregg:
I would bet that it is a lead acid battery; or what is left of one. The pointed electrodes are to penetrate a rubbery coating on a rescue strobe and the acid would be in a separate plastic bag or thin glass ampule to be broken and activate the cell. Probably from an air force parachute harness or perhaps a weather balloon.
