       I'm not sure what this little beasty is.  I'm counting 6 leads and there are no markings.  My best guess is an RF relay.#hamradio

       @penguin42 Might be an opamp.

       @penguin42 In Soviet Russia, they used to put op-amps into casings like this.

       @penguin42My first guess, from the can and the tab, would be an old op-amp.  I'd start by measuring resistance all legs to all.  That would find a relay coil, if present.  Then a >1V continuity checker lead to lead and reverse to locate junctions.  Also, one lead is probably grounded to the can.
