Back from the flea market. Saw a parts washer, and to the right of it a custom parts tray. After the parts were washed the clean parts were put in the tray - I mean wagon. When I first saw it I thought the wagon bed was just laying on top of the sewing machine stand, and tried to lift the bed to see if there was a sewing machine underneath it. But they were bolted together.
I asked they seller what happened to the rest of the Singer sewing machine. And we both laughed.
