Revolution Counters

Page 13 Instruments

RAF Wartime Rev Counters measure engine revs and are generally generic instruments, the aircraft shown in our adds did use the ASI's shown but they may of coarse been used in a different type of aircraft with matching performance for that date. If you are not sure what Rev Counter you require then please contact us and I will do my best to advise you on the most suitable purchase. Bombers and Fighters generally used different styles of Rev Counters.

Hawker Fury RPM Gauge (Pg 13 Instruments Rev Counter 1)

Superb boxed early RPM gauge dated 1938. Used in the Hawker Fury.

Avro Tutor Rev Counter Hawker Fury RPM Gauge (Pg 13 Instruments Rev Counter 2)

This RPM gauge was used in the Avro Tutor. Probably used in other 1930s aircraft with the same engine.

The Tutor was designed as a replacement for the Avro 504 trainer. The prototype was fitted with the lower powered Armstrong-Siddeley Mongoose engine, but production aircraft were fitted with the Lynx engines. The Tutor entered service with the RAF in 1933 and from 1933-36, Tutors from the Central Flying School were famed for their impressive formation aerobatic displays. Tutors were also used throughout the RAF as elementary training aircraft

Contacting Rev counter  (Pg 13 Instruments Rev Counter 15)

This is a really unique item a contacting rev counter. I have never seen one of these before, it is definitely wartime as it has a Kings crown stamped on the back so manufactured before 1944. This may be for a test aircraft as a contacting unit usually activates an audible warning when a pre set limit is reached war, contacting altimeters are used on dive bombers to warn the pilot when its time to pull out of a dive so this may have a similar function by warning the pilot a pre set RPM limit has been reached.

Hampden Rev Counter  (Pg 13 Instruments Rev Counter 16)

The Hampden was the last of the twin-engine medium bombers to go into service during the expansion of Bomber Command in the late 1930s and, together with the Wellington and Whitley, it bore the brunt of the Royal Air Force's attacks against Germany in the early years of the Second World War. Better manoeuvrability and performance than its two contemporaries led to high expectations, but early war time operations proved the aircraft had serious deficiencies. Two particular problems were identified. The very narrow fuselage provided cramped accommodation for the crew causing fatigue on long missions. Unlike other British medium bombers the Hampden had no multi-gun power-operated turrets. Its fixed forward gun was next to useless and the three flexible gun mountings in the nose and fuselage had a limited traverse which produced a number of blind spots. Modifications were put in hand to provide more guns but the fuselage design remained a problem throughout its service life.
After a disastrous, but mercifully short, daylight campaign Hampden's were switched to night operations until 1942 when a number were converted to carry a torpedo. Eventually 144 aircraft were modified in this way and the type continued in service with Coastal Command as a torpedo bomber until December 1943.

Please note it has come to my attention that this gauge was also used in other early Bombers including the Wellington and Anson.

Jaeger WW1 Rev Counter (Pg 13 Instruments Rev Counter 20)

This is a very nice Jaeger rev counter believed to be used in WW1 aircraft. It reads to 2200 RPM with a rev limit of 1850 this is consistent with the revolutions produced by early aero engines see pictures. In good original condition.

This is an SE5A Cockpit. Although the rev counter is a modern replacement (Flying Reproduction) you can see the rev limit is just under 2000 RPM

Another SE5A cockpit what a variation from the one above . Click on the picture to enlarge. The RPM counter again does not look original.

You can enlarge this click on picture.

New information leads me to believe This instrument was used in early Bentleys and may have doubled up as an aircraft rev counter however I cannot be sure that. I have been told by a Bentley collector that these change hands at up to 700 so still a good buy.

Smiths industries Rev Counter A.T.R.C (Pg 13 Instruments Rev Counter 27)

I have spent quite a bit of time trying to find what this was used for. It looks like a classic car gauge but has an air ministry stores reference.

A.M  42 FF/69

It has a solid brass case. Its a type A.T.R.C 85 made by  Smiths industrial instruments who were a sub company of Smiths and Sons and was formed in the 1940s

The A T R C stands for auto temping racing competition and are high quality and very accurate instruments usually used on racing machines. I tried to look up the pattern number which appears to be quite early but could not find the specific numbers.

If anyone has any information about this instrument please contact me.

 Rev Counter generator MK IV (Pg 13 Instruments Rev Counter 31)

This is a rev counter generator they converted the rotary movement from the engine to electrical to drive electrical rev counter's in aircraft where the distance from the instrument panel was to far to practically use a turning cable drive. Lancaster's use this type of generator along with other heavy bombers, transport aircraft and twin engine aircraft like the Mosquito. The fitting on this generator is the same as the standard rev counter drive and a short cable attached to the engine was connected to the generator unit from there electrical cables were connected to the rev counter on the instrument panel.

Rev counter from Vickers Valletta WJ 477 (Pg 13 Instruments Rev Counter 40)

This rev counter has a small piece of tape where you can just make out the serial number WJ 477 this makes it from a Vickers Valleta. This aircraft first flew in 1952 and was destroyed at RAF Scamptons fire dump.

The Valetta C.1 entered service with the RAF in 1948, replacing the Dakota with RAF Transport Command and with transport squadrons in the Middle and Far East. The Valetta was used to carry out parachute drops in the 1956 Suez crisis as during the Malayan emergency and operations in Aden.
