I have a White Rotary electric sewing machine number 35X2984. The electricl motor was Patented November 8, 1927, Cleveland, Ohio U.S.A.
This machine is in working and has been well taken care of. Was wondering if anyone could tell me about the time the machine was made.

I have a Electric White sewing machine with the number FR 2386758 and on the back it has 874 A+, I would like to know what year it is from?
