Altimeters

RAF Wartime Altimeters are 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 Altimeter you require then please contact us and I will do my best to advise you on the most suitable purchase. The altimeters are described as accurately as possible but would require a full inspection before being used for flying and all items are sold as such.

Stuka JU 87 altimeter (Ins pg3 Altimeter 1 ) 

Here is a altimeter used in the JU 87 the infamous Stuka dive bomber. It appears to be in good working order the needle moves when the knob is turned. Also used in the AR 234 the worlds first operational jet bomber.

Mk XIII Altimeter (Ins pg3 Altimeter 3 ) 

Here  we have a Mk XIII altimeter in very nice condition and dated 1943. These altimeters work on the aneroid principle and are known as simple altimeters the altimeter is calibrated to isothermal law which assumes a constant temperature of 10'c at all heights. This tends to give large errors. This altimeter was being replaced in operational aircraft at the outbreak of war. However they remained in service for many years and are sometimes seen in the pilots position in larger aircraft i.e. Sunderland and Stirling.

Altimeter Mk XIII  (Ins pg3 Altimeter 8 ) 

These altimeters work on the aneroid principle and are referred to as simple altimeters. The altimeter is calibrated according to isothermal law, which assumes a constant temperature of 10 degrees C at all heights. The altimeters tended to give large errors at height and a computer is required to establish a true figure. This range of altimeters was gradually replaced in operational aircraft at the out break of war.  However they remained in service for many years and are sometimes seen in in the second pilots position of larger aircraft including the Sunderland and Stirling.

Very Early pre War Dated 1936

The Blackburn Skua was an idiosyncratic aircraft. Designed for the British Fleet Air Arm to perform as both fighter and dive bomber, it performed neither task particularly well.

Nevertheless, the Skua had the honour of being the first British aircraft to claim an aerial victory in World War Two. The victim was a Dornier Do 18 shot down by two Skuas on 26 September, 1939. Skuas were also responsible for the destruction of the first Axis capital ship of the war, sinking the German cruiser Konigsberg in 1940.

Mk 111 A Altimeter Contacting Dive Bomber Altimeter (Ins pg3 Altimeter 9 ) 

A contacting altimeter gives a warning or signal at a pre determined height. The Mk 111A  shown here was standard equipment in a number of Fleet air arm dive bombers. The purpose of this altimeter was to warn the pilot to pull out of the dive. Very good original condition.

Grumman Avenger altitude switch (Ins pg3 Altimeter 10 ) 

Here we have a mint condition altitude limit switch. This aircraft used as a torpedo by both the RAF and USAF famously during the intense carrier battles of the Pacific war. This instrument  assisted in attaining the correct height for torpedo drops.

The Avenger entered U.S. service in 1942, and first saw action during the Battle of Midway. Despite losing five of the six Avengers on its combat debut, it survived in service to become one of the outstanding torpedo bombers of WWII .

Airspeed Contact unit 1939 (Ins pg3 Altimeter 11 ) 

This is the first instrument of this type I have seen, it is similar in design to the contact altimeter which gives the pilot an audible warning at which ever altitude it is set. My best informed guess is that instrument is some sort of stall warning instrument and would give a warning at the set airspeed.

Dated 1939 is in good condition apart from some slight damage to the plug connection as seen in the picture.

Altimeter for Link Trainer (Ins pg3 Altimeter 20 ) 

Here we have a quality altimeter for a link trainer which were used to train wartime pilots.

It has a metal case as apposed to bakelite for the flying version. The face is identical to the classis wartime pattern used in practically every British Wartime aircraft including the Spitfire. It would be fine to fit to a static panel. Its dated 1948 but this is a service date and its almost certain this was produced during WWII.

The hands move freely when the knob is turned.

Altimeter fitted to Spitfire's Hurricanes and practically all other RAF Wartime aircraft. In poor condition see pictures mounted in a wooden base.

This picture below was taken from the Pilots notes for the Spitfire MK IX but used in all Mk's up to at least Mk IX. Some later Spitfire's used green faced altimeters shown in the listings below.

WWI RFC Aero Altimeter (Ins pg3 Altimeter 29) 

This is a superb and rare piece from WWI the Compensated Aero altimeter was worn on the wrist and read to 10,000 ft. Worn by aircrew during WWI it has an extra long strap to enable it to be worn around flying glove. This type of compass was in use from the earliest days of flight before instruments were fitted to aircraft  It is in excellent condition and work's well. The bezel rotates to allow calibration

 

Under is an article from flight magazine of 1915 showing a similar wrist altimeter. These were precision instruments and hugely expensive at the time the example shown below being for sale at 3 17s 6d in 1915 the equivalent today would be over 900.
