Standard Rotary help please
Hi,
I have what I believe to be my Great grandfather's Standard Rotary sewing machine. As a genealogy buff I would love to figure out if it was his and used during his time as a tailor or if it is more likely my grandmother's. The serial number is 778344. My goal is to restore it but don't want to touch anything until I have as much information as possible.
Thank you in advance!
