I have come into possession of a white rotary machine, the only numbers I can find on it are on a small plaque on the front with the letter/numbers "FR 3411776", am trying to date the machine, any answers?

http://www.geocities.com/claw.geo/smw.jpg If you have a White sewing machine, call the White toll-free number at 1-800-446-2333. If you provide them with a serial number (for White Rotary machines, the serial number begins with an 'FR' and is stamped on the back right hand side of the machine bed), they should be able to provide you with an approximate date of manufacture.

I tried calling the toll free number for White, and the lady told me that they can't look up information on a machine that old.

Go to this site. It is a plethora of wonderful information on treadle sewing machines.
