This Multimeter came in bad shape: Dirty, glass loose, case-edges broken and
not woking.  After soldering  disconnected wires, there was a surprise:  The
Volt- & Amp- Ranges are extreme precise!  But the Ohm-Ranges were off. There
was a broken resistor and a bad one.  Both replaced (by trial-&-error) until
good results were accomplished.

 

To repair the broken case, inner forms were made of aluminum strips, hold in
place by  chewing gum. Tapes made the outer forms. Than 2-Component-Glue was
filled in between ...

          

After hardening, the final form was filed out ...

          

... and finally painted with black marker. The glass was fixed & sealed with
a frame of cardboard. The damaged plugs were replaced by  RED  & BLUE  ones.
