Patent 1907 F. Englehardt & Sons by The Holtzer-cabot Elec. Co. They guy I got it from said it didn't run. It's a project. I can't imagine trying to find one of these things if you need one. There is nothing worse than looking in the machine and seeing a new washing machine type motor in an otherwise nice unit. This will make a good restoration piece. Check out the photos for condition. It measures approximately 5 3/8" X 3 1/8" center to center on the mounting base.
