Prestolite and Autolite Distributors ?
Auto lite are the earlier usually pre 60, prestolights are usually cast iron and dual point but can be found in single point also usually in Canada. Yours should be a early aluminum with a oil cap on the shaft. The cardones can be good but keep in mind they are kind of generic, and are set up for a span of years, and never have numbers on them.
Prestolite usually industrial.
