A co-worker has a Singer in a cabinet that she says her dad brought home about 1950-51. she says it's black and the serial # is JC719092 I haven't seen it and she's not sure of the weight. From her description it doesn't sound like a Featherweight?? She does say it only sews a straight stitch. She'd like to replace it with a newer model that has zigzag and some other features. I'm interested in a Featherweight and told her I'd buy it if it was one. I can't find any website that shows what this really is. Thanks for your help.
