I'm having problems with Photo bucket at the moment so was trying out Flickr. The item no. On eBay is 191592089525 and I suppose it is more or less the same but with an added lcd display?
looks more like an LED display to me - the one in your first post has one also?
I'm still going with 10K for the CV pot - the marking on the top - W103 - I think is the value, in the absence of any other visible number.
The way it works is the first 2 digits are the start of the value and the last digit tells you how many '0's to add so 103 = '10' + '000'. i.e. 10,000 Ohms, or 10kOhm.
The marking at the bottom of the face next to the CV print show you which pin is which - the value will be between the outer pins.
If there wasn't a pin out, if you take it out of the circuit, then call the pins A,B and C for example. check between each pair, so A-B, A-C and B-C.
The largest value will be between the track ends, and is the value of the pot.
