Originally developed as a dashboard-mounted timer for rallying and other pursuits, such examples were also issued and used in various types of
RAF and
RN aircrafts. Best known for their use in
Harrier Jump Jets (as these lacked cockpit clocks), the
3B/3822 was perfectly suited instrument for long-range timing - attributed with the designation "A" Stores, "V&A". The “A” served to indicate that a replacement would only possible if the original was returned damaged or otherwise unserviceable, with “V&A” requiring the timer be locked away, when not in service.
Used in a variety of applications - from the aircraft cockpit to the evaluation and timing of missiles - legibility in low-light conditions would have been one of the critical elements, sought by the
Ministry of Defence when issuing such timers. As indicated by the large 'T' below the centre stem, both the minute and seconds hands show tritium material at their tips, matching the large Arabic numerals on the dial. Operated by three pushers, the jumping hour-disc, minute hand and seconds hand complete the utilitarian look and feel, with a rotating bezel offering pilots extra timing capabilities.
This particular example is in 'new old stock' condition, in its original, partly-opened but unused plastic seal. It also comes with its original cardboard box, inner padding and instruction paper. Rather charmingly the box reads, "Not to be opened until required for use".
