Just found the Model number: 3 FR 3216661. DH just got the machine out of the cabinet. Hinges behind the machine were pretty rusted. Lovely mouse nest in the bottom of the machine. Lots, and lots of grasses. Did get the bobbin out. Motor's not froze up. Found a list of model numbers. It's after 1923. The numbers progress at about 1,000,000 per year. So forwarding 2,000,000 makes it somewhere in the 1925-26 range. Anyone have any better info.
Thanks
