Toyota sewing machine (Haddington EH41)

The machine will sew and sounds ok.
The machine uses a battery to power the bobbin winder which has been left in the machine too long and has started to corrode. Some wire wool to the terminals should fix that.
There is a manual and original box - I think.
I picked this up from freegle but it is not fully working.
An easy fix for someone else.
