Just going through my small collection of analogue
multimeters to see if they are in a usable condition
and for calibration if necessary.
Since my BBC Goerz Metrawatt MA 3E is slightly off,
I have unsuccessfully searched the usual sources
(elektrotanya, radiomuseum among others) up and
down for two days now for the schematic.
The manuals I have for the MA 3E do not include
any schematics.

Thus I am asking the esteemed voltnut community
for help. Does anyone have any schematics for this multimeter?
Enclosed two pics of this multimeter to jog your memory perhaps.
PS.: I can offer to the community redrawn schematics of the
"Metravo Electronic" multimeter if anybody is interested.
