The Vade Mecum -- go with me -- lug pattern was introduced in the 1953 catalog with round fork blades. The 1956 catalog showed the VM with oval fork blades. The original Vade Mecum design was still in the 1962 catalog, and was produced until 1963.

The 1964 catalog replaced the original design by three new ones, designated VM Mk I, II, and III.

There was a fourth variation (also from 1964), called the VM Superb; few frames are known to have been built with this pattern. See Rare Models.

Over 100 VMs (including Mk I, II, and III) are listed in the Hetchins Register.
