Dennis Turk guesses it's a prototype,
because of it's odd features like a 2" x 8tpi spindle thread,
The spindle thread is an exact match for a Cincinnati dividing head,
I got the lathe from a guy in Alameda, CA,
He got it from Alameda high school,
LeBlond told me it was shipped to Flanagan Machinery in San Francisco in 1926.
