It hadn't been used for a long time when I got it. It was a bit grimy and stiff, and over about a fortnight I cleaned it up. This is the machine that I learnt so much from. Once it was oiled and running it was an absolute joy to sew with.
Eventually I made the Youtube videos to show that with very basic equipment, anyone can clean up an old sewing machine - provided it isn't rusty or otherwise too far gone. You don't need a workshop and fancy tools. I do all my tinkering on the dining room table - well covered with old newspaper of course.
