Hetchins's catalogs were not dated. In dating them, we go by what models are introduced for the first time (correlated with early sales in the ledgers), and prices. Len Ingram writes of this catalog: "This catalog states that the Vade Mecum is a new model. It came in ca. 1953/4." The catalog lists frames as well as complete bikes for sale, but components are no longer listed.
