Brunsviga 13RM

This calculator was bought in nearly mint condition.  As often, it has probably been stored for decades because which of some parts didn’t easily move.  After thorough cleaning and a bit of new thin oil it runs well again.

These photo’s were taken after a 2nd clean job. This and other mechanical machines tend to work well after a first maintenance job but after a year or so some parts tend to get sticky again.  May I should use them more often :)
