Thank you Jon! Darn, what a great site that use to be for identifying White's and dating them! Treadleon has a limited amount of dating of the White, but nothing like we use to find on the Arachnesobsession site! It is a shame when something so informative is taken away from all the collector's. I only have one Rotary Electric Embossed Black Crinkle White machine from 1931.
Modern Home come to think of it, your White is very similar to my White and mine is a Rotary Electric! Your machine is not the embossed style, but it sure looks similar.
