This has been cleaned and serviced and runs as smooth as silk. It is all original other than the label which is a perfect copy of the original. I have only ever had a couple of these 4 terminals dials as they were quickly upgraded to 5 terminal and so probably were only produced for around 6 months. Note the enamel has some hairlines as can be seen in the large format pictures.
