I have an antique hand crank sewing machine (brand name STERLING ) possibly made by the Singer company in the early 1800s. It belonged to my dad's grandmother (my dad is 85 years old). I tried to get info. on the web but can't find any. Does anyone out there have any idea about this brand of machine. I can't find a serial number anywhere on the machine and would appreciate any help you can give me. Thank you.
