Marked AG009250.
For sale is one incredible Vintage 1940s (1941) Singer 221-1 Featherweight Sewing Machine that is Complete and Working in original carrying case.
I have plugged it in and it works. I inherited this sewing machine and do not know much about sewing with these older machines. The case locks perfectly. The case handle shows signs of wear and age but is in tact.
I know that this machine was regularly serviced. If you have any questions please ask and I will do my best to answer.
