This is a Singer featherweight model # 221J made in St Johns, Canada 1961. Serial # JE154076. Numbers starting with JE were among the last to come from the St. Johns factory which operated from 1904 – the early 1960s. There’s a myriad of history and information on the web around these machines as they’re highly prized and collected. As far as I could tell the 221J is a version of the 221K, the third iteration of the machine. 221 were and still are prized for having the capabilities of a full size machine, including attachments, in a relatively light and compact piece. Traveling seamstresses, club quilters and collectors still covet these machines today. I am not a sewing machine expert, but know enough from growing up with a mom who sewed everything to thread and run this machine. It threads much the same as larger, later model Singers.
