Freshly imported from Japan (and the box never opened) the 60mm Temp meter ( either oil or water) with a white face is yours for the best and most sensible offer I get. The instructions are in Japanese but I can give you the important wiring details and the rest is in pictures. Comes with the necessary sensor.
This was available in the last Demon Tweeks catalogue for £190 ! !
