... the "MATHEMATON" came dirty and rusty

It consists of 2 Parts:
The UPPER PART is the manual-operatable CALCULATOR
( shown upside-down )
and the LOWER PART is the MOTOR UNIT
Both clipped together on the sides ...



... A 10s-CARRY-UNIT with its SPRING and broken SUPPORT
fall out of the CARRIAGE



Disassembling the "Area-In-Question" ...

Made a SUPPORT BEAM out of a Sheet-Metall Strip - glued-in ...
