Set of 6 original stainless steel Mersey lock keys in the rare 14-lever laminated pattern.
These are genuine vintage Mersey-pattern safe/security keys associated with high-security British lock systems supplied across government, MoD, PSA, military, naval, utility and commercial environments by makers such as WLN, Chubb, PSA and Crown Suppliers.
Unlike the solid brass versions, these are the laminated stainless steel type, made with stacked bit plates around the key stem. Stainless examples are much harder to find than standard brass keys and are especially desirable for collectors, safe engineers, locksmith displays and historic British security hardware collections.
This is a random-number set rather than matching pairs.
Good original vintage condition with light surface marks, patina and storage wear.
All six keys are straight, structurally sound and free from cracks, breaks or obvious distortion. Laminated bit plates are intact and secure, with no obvious loose sections.
Stamped numbers remain visible, and the stainless steel surfaces show normal age-related marking consistent with historic use and long-term storage. Sold as collectable historic Mersey lock keys, exactly as shown.
