I have a Singer mdl 66, serial number AF 727967, dates to December of 1940.
It's painted with black crinkle paint. Has the vertical stitch control with the back tak reverse. And at some point someone, or the factory has put a shiny black belt guard / bobbin winder assembly on it.
Now, one just like it but painted with normal shiny black paint is a 66-16.
So, my question is: Is Mr. Crinkle still a 66-16 or what?
