The instrument as received appeared to be in perfect condition and
unopened since the day it was made. However it refused to operate an
any range and the red overload indicator could not be reset. Once
opened the cause was immediately apparent as can be seen in the picture
above. The meter had obviously had been dropped or suffered a severe
blow sufficient to part the magnet and dial assembly from the moving
coil and pole pieces. I removed the meter completely and aligned the
parts as best I could but the hairspring is now distorted and although
the meter deflects it reads about 60% of the correct value and the
movement catches the pole pieces preventing full scale deflection.

What is it worth? These are fairly rare so possibly about £40 perhaps more if case and leads are included. A model 8 would be a better buy.
