Singer model 66K symaskin

This machine:

Singer 66K Nov 15 1930, if you look inside the cabinet you will find a shank of iron that fits in the little hole in the front down on the right hand side. Little bit of sewing machine oil (Clas Ohlson , PRESSOL Oil) put 2 drops in every hole on top of the machine, wait 2 days and start sewing :)

A true gem in the history of sewing machines
