This is a Plymouth sewing machine. It is a class 15 Singer clone made in Japan sometime in the 1950s or early 1960s. She was my first vintage sewing machine and cost me $18.99 at Goodwill. She needed a foot controller and belt and only minor cleaning but all is fixed now. This machine was the start of my collection of vintage sewing machines. Eventually I will put her in a cabinet as she came as is, without a case top and broken hinges. Her name is Patience.
