The Mersey is a lever lock made by the North Atlantic Treaty Organisation (NATO) Ministry of Defense (MOD). It features a distinct puck shaped housing which is designed to fit on safes used by the MOD. The Mersey can also be identified by its V shaped key which actuates two independent sets of levers inside the lock.
General
The NATO Mersey exists in two distinct guises, each with some evolutionary revisions: the 10 lever variant and the 14 lever variant. Both locks share a number of common security features having a common ancestry. Made for the North Atlantic Treaty Organisation (NATO) during the 1970’s through to the 1990’s, these locks use a unique V-shaped key.[1]
In some instances, the keys for the Mersey were stored in a key safe protected by a Mark IV Manifoil combination lock.[2][3]
