This motor is a single speed version of the Model 10.

There aren't many of these around. (Probably everyone wanted the 5 speed.)

This photographed example is the only one that I have ever seen with a decal on it that proves what it is!

example 1: Serial # D1068 Note: I can't find any ads or references to the single speed Model 10 so this is a really empty page! e are lucky to have this motor.
