I am the owner of a South Bend lathe that is serial number 52012.
I believe that means it was manufactured in 1933.
It has a 9 inch swing and a 3 foot bed. Catalog number 22-YB.
I purchased it from a man that was one of the original owners
of a company named Midway Electric in St. Helens, Oregon.
I have owned it for about 30 years and use it often for hobby purposes.
