Help identifying temperature senders

I'm clearing out my garage and have found a couple of senders. I bought them to fit to my old Mk1 GTi, but ended up selling the car instead.

Does anyone recognise them? I think one is oil temp and one oil pressure, but I can't remember.

The smaller one has FAE 32110 U02 stamped on it, and the bigger one has nothing. Any help would be most appreciated.

yes top is oil pressure, bottom is temperature, i recall the temperature is marked on the edge, as its similar to water temp.   

Top is the oil pressure sender for the center console and the Low oil pressure at Idle switch.

The bottom is a temp sender for oil/water.
