Strange microphone - Google search leads nowhere!

Okay, thanks for the info. I'm going to try using it anyway to see if it's any good.

May or may not be wired like the link below. This is typical of how a communications mic might be wired to key a transmitter. Try pins 1 and 2 for audio and change the position of the switch if it doesn't work.

even some EV mics originally used connectors like that ...... the mere fact that it's a 4 pin connector doesn't automatically mean it's a POS.

Any ideas as to what it is, how much it's worth, and what type of plug I'd need to hook it up?
Thanks.

Well I just gotta ask you this, RCTM .....
Does this microphone have any weight at all to it, or does it feel light and cheap?
