I found the information about National and thought Aha! But the machine was supposedly a hand model only, and this is a treadle, and the owner says that Singer is etched into the underside of the bed. Since that Amazon was an inexpensive machine in the first place it is strange that someone might put that gold paint on an old Singer. The owner is looking to see if there is a serial number. I don’t have the pictures of the machine, it is on the Facebook merchandise pages for the Portland, Oregon area, and Hillsboro, Oregon particularly.
