Got this at a car boot sale its a mimesis pickup to go over the sound hole of my guitar , I haven't got a clue how to wire this up  and I am not sure what the metal thing is. 
If anyone can help would be very grateful .

It seems that the shielding wire goes to sleeve, and the two other wires go to tip and ring for stereo out. I've done this for mixing pickups, using a figure-8 stereo cable to a mixer-preamp, eg a Baggs Mixpro. Not sure from that link which wire, red or white is magnetic, and which is white. A bit more research should find it.
