We went to the flea market to day and a lady had a Singer model 15 Ser#AD581004 made in Feb. 14, 1934. The machine looked really good but ofcourse needs cleaning. The machine was in a cabinet with a knee control. It had all the attachments minus the buttonholer. Was asking $20.00 but came down to $15.00. We don't really need any more sewing machines especially electric.
