This is a superb and rare eight day clock dating   from 1937. This is the larger diameter type of clock measuring 95mm at its widest point. Nicely dated 1938 pre Battle of France and  Battle of Britain this type of clock was used in the early MKI and II Spitfire and I believe also the early Hurricanes main instrument panel. This clock functions well and is mounted on a display plaque.

Seen left a very Early Spitfire, note the two blade prop.

This is an early version of the classic climb and descend indicator with a 1940 date. This instrument can be identified by its deep body. In nice original condition. Not to be confused with the similar post war version.

Here we have a 16LB boost gauge with a Battle of France 1939 date. 16lb Boost was not introduced on Spitfires until the MKV was introduced in 1941. It was therefore used on some other aircraft type capable of 16Lb Boost in 1939 or a pre production run for the MK V seems unlikely in 1939 though. This instrument has clearly been used I wonder what stories it could tell. Buy a piece of aviation history with a very desirable date.

This is a superb highly collectable classic altimeter with a Battle of France 1939 date. This instrument has a 1944 service date so it appears to have been in operational use throughout the war. Fitted to practically every type of RAF wartime aircraft with this date it could also have been fitted to a Bolton Paul Defiant along with the early Spitfires and Hurricanes. The hands move erratically when the knob is turned and would need a complete overhaul to work properly.

  In December 1939, 264 Squadron at RAF Manson was the first to be equipped with the Defiant Mk I. The first operational sortie came on 12 May 1940 during the evacuation of the British

expedionary force from Dunkirk. The Defiant was initially successful against enemy aircraft. Its high-water mark was on 29 May 1940, when No. 264 Sqn claimed 65 kills, mostly JU 87 Stukas and Messersmitt 110 twin-engine heavy fighters.

The 480 MPH Airspeed indicator was generally introduced in the MK V Spitfire onwards. This one however is dated 1939 which makes it too early for MK V application. Research leads me to believe that this ASI was most likely produced for the very rare MKIII. Introduced in 1940 but not made operational until 1941.

The Mk III never went into full-scale production. It was to be fitted with the Merlin XX engine, which developed 1,390 hp and so the fuselage and engine mountings needed strengthening, as did the main gear legs.

A retractable tail wheel was also incorporated. The most radical change was the cropping of the wing tips in an attempt to improve the aircraft's rate of roll, even at the expense of radius of turn.

 Armament was to comprise four 20mm Hispano cannon, the machine guns being removed; but although intended as an air superiority machine par excellence, the Spitfire III was to be overtaken by the events of war.

 A top speed of 385mph was achieved in level flight.  so a 480 MPH seems to be a suitable margin for this aircraft. The 400MPH ASI fitted to the Mk I and MK II would not be suitable for this aircraft. The MK IX was only 25MPH faster at 410MPH and was also fitted with the 480MPH and this ASI continued in Spitfire's throughout the War in all Mk's.

It is also possible these were also used in early PRU Spitfire's which also had superior performance to the combat aircraft in service . I cannot find any performance figure's at this time for the MK II PRU Spit's.

The fact is all 480MPH ASI's are hard to obtain, but  with 1939 date, make's this one practically unique. So far I have never seen another 480MPH ASI of this date and neither has anyone I have spoken to making this an extremely  desirable piece of Spitfire heritage.

GLOSTER GAUNTLET 240 MPH ASI (pg 23 ins)

A very rare Airspeed indicator used in the Gloster Gauntlet. Not many instruments like this survive from the 1930s this is in mint condition . Fighters were about to take a huge leap in the form of Spitfires and Hurricanes. This ASI was in use two years before the first Spitfire prototype flew. The Gloster Gauntlet was designed by H P Folland to meet RAF requirements for a new day-and-night single-seat fighter during 1927 and entered production in 1934 to Specification 24/33. A total of 24 Gloster Gauntlet I's and 204 Gloster Gauntlet 11's were built for the RAF, with 605 hp Mercury VIS engines and two fixed for-ward-firing 0.303 in (7.7 mm) machine guns. A handful remained in service with No 616 Squadron in September 1939 but were soon retired from front-line squadrons, continuing to fly in the UK as station hacks and for meteorological duties. A few others equipped 'D' Flight of 47 Squadron (later No 430 Flight) in the Sudan and saw combat in 1940, against Italian forces; ex-RAF Gloster Gauntlets also operated briefly in North Africa with RAAF squadrons and in East Africa with the SAAF. 24 ex-RAF Gloster Gauntlets supplied to Finland in 1940 served as fighter trainers until 1945, some on skis.

Here is a used 8Llb Boost gauge which I am reliably informed is attached to a fragment from a MKI Beaufighter instrument panel at least that's what the dealer I got it from told me. It has a part number on the panel you can see it, you can enlarge the image by clicking on it. The date supports its use in a Mk Beaufighter.

Official trials on the Beaufighter commenced at an all-up weight of 16,000 lb. after the first prototype's delivery to the RAF on April 2,1940, and a maximum speed of 335 mph was attained at 16,800 feet. Also suitable for a battle of Britain Spitfire or Hurricane panel.

Jaeger WW1 Rev Counter(pg 23 ins)

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

Any further information gratefully received discounts available for info supplied.

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.

Any further information gratefully received discounts available for info supplied.

Here is a an altimeter as used by Spitfires, Hurricanes and practically every wartime RAF aircraft. Dated with a 1939 battle of France date. The hands move freely when the knob is turned but the case rattles like a box of mechano so I do not think it will be serviceable.

This instrument is in good condition and the face turns when the knob is turned.

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.

Here we have a 320 MPH ASI dated 1940 in good condition

This is like most instruments is generic and would have been fitted to a range of aircraft with suitable performance. This type of ASI was also fitted to the Fairey Battle shown above.

The Fairey Battle was one of the most notorious aircraft of the WWII. During the German invasion of France in 1940 the Battle squadrons suffered very heavy losses during a series of desperate attacks on the German spearhead.

The Battle was designed to replace the Hawker Hart light bomber. In 1933 the Air Ministry wanted an aircraft that could carry two crew and a 1,000lb bomb load for 1,000 miles at 200mph.
