The White Rotary and the Singer Featherweight are a couple of machines I was working on over the weekend. Incredibly different machines!
The White hadn't been used in many years (would be my guess), as it was in need of more than a basic cleaning. Lint had compacted under the throat plate, and there was a rat's nest of bobbin thread behind the bobbin.
As well were frayed wires requiring a complete rewire of the machine.
The Featherweight needed a more basic cleaning and a new belt. These are highly prized by sewing-machine collectors, and it's easy to see why. Lightweight, fine quality and a pleasure to work on.
