1951 was the first year for the new Teleglide front end. This Catalog was revised mid-year to show some mid-year changes.

One example of the January issue has the words "Add 5 per $1.00" rubber-stamped on the top of each page, but an example of the May issue has the same prices as the January issue. The rubber-stamping may have been done by a dealer and not by the factory.
