Vintage RAF Smiths Mk 22D Servo Altimeter 6A/4339168 – 1965 Cold War Jet / Comet / Canberra / Vulcan Era

A genuine ex-Royal Air Force Smiths Mk 22D Sensitive Servo Altimeter, manufactured in Great Britain in 1965 and carrying official MOD / AID inspection markings dated April 1974. 

The Smiths Mk 22 series was the iconic counter-pointer primary altimeter fitted across British Cold War cockpits. 

This specific 0–60,000 ft variant (Ref. No. 6A/4339168) was catalogued for high-altitude RAF jets and transports including the de Havilland Comet and English Electric Canberra, and shares the exact bezel, dial styling, and Smiths Flight System architecture used in early Avro Vulcan, Handley Page Victor, and English Electric Lightning cockpits.

Dial & Glass: Very clean, bright markings with crisp counter drums, clear failure flags, and intact front glass with no cracks or clouding.

Controls: Lower barometric millibar setting knob turns smoothly and adjusts the bottom subscale window (0835 mb shown).

Casing & Seals: Original black military finish with clear yellow "Unified Threads" stencilling, intact factory copper anti-tamper wire seal on the housing bolt, and original black electrical cannon plug cover and blue static port dust cap still fitted.

Data plates are clear and legible.

Functionality: As a servo-driven instrument requiring an external 115V 400Hz AC aircraft supply and amplifier, this unit is untested and sold strictly as a static cockpit display piece, restoration project, or aviation collectable.
