This belongs in the instruments section as it is closely related to RPM indicator's listed in these pages.

RPM Counter drive(pg10 ins)

This is in superb boxed serviceable condition (subject to required check's and permits only opened for the picture and immediately resealed. These drives were connected to the Merlin by the normal direct drive cable that  powered the mechanical Rev counters .It generates an electric current and power's the electrical type RPM indicator. This  type of indicator was used where it was impractical to use direct drive cable's. They were used in all Mk's of Lancaster's and many other Bombers where the cockpit or engineers panel was far remote from the engine. It was actually used to power the RPM gauge in the rear cockpit of the very rare two seat Spitfire's. These do appear from time to time but never in this condition, this should end up on a flying aircraft.

The first Griffons had single-stage superchargers, and were fitted to the Spitfire MK XII.

These aircraft arrived just in time to take on the Focke-Wulf 190 "Tip and Run" fighter bombers that were attacking England's South Coast. Their impressive low-level performance was used to good effect.

For high altitude a two-stage supercharger was needed and these arrived in the Spitfire XIV

and XVIII. This enabled the Spitfire to stay in the forefront of fighter performance until the end of the war

Rolls Royce Griffon Engine Rocker Cover 1 (pg1 pwr)

This is a  rocker cover from a Rolls Royce Griffon. The Griffon was a 36 Litre monster replacement for the Merlin, its in good condition with some cracking to the paint but overall perfect for display.

The cover is straight.

RAF RCAF (MERLIN ENGINE) RADIATOR SHUTTER THERMO SWITCH (pg1 Pwr)

LANCASTER BOMBER MERLIN ENGINE RADIATOR SHUTTER THERMO SWITCH. THIS SWITCH WAS REMOVED FROM LANCASTER BOMBER FM 215 AS TIME EXPIRED OCT 26/1959.

Superb item with great provenance, connection to both Merlin and Lancaster. A very rare event is to have a picture of the actual aircraft a part has been removed from, the part was almost certainly in situ when this picture was taken of

Lancaster  FM 215.

History of Lancaster FM 215

TOS 21.8.45 in RCAF; was the 4th. Converted by Avro Canada to Mk.10P; issued to #408(P) Squadron with code 'MN215'; did extensive test on SHORAN; was used for short time at Winnipeg as a SAR aircraft with #111 Composite Unit about Aug. 1959; SOC 28.9.62

Rolls Royce Griffon Valve (pg1 pwr)

Here we have a Rolls Royce Griffon valve.

The Griffon engine followed the Merlin into the Spitfire starting with the MK XIV and other front line WWII and post war aircraft. At 36 Litres it was considerably more powerful than the Merlin whilst being physically slightly bigger. The Griffon went on to power RAF aircraft into the 1950's notably the Avro Shakleton.

 

Shown above the Mk XIV Spitfire fitted with a Griffon engine , note the bubble canopy 5 blade prop larger tail and slightly extended nose to accommodate the extra power and size of the Griffon.

Spitfire/Hurricane engine plate (pg1 pwr)

This brass plate is an unused BLANK cockpit engine data plate typically fitted to large numbers of 2nd WW British aircraft, especially in the early war days.  They were usually riveted to the cockpit side, alongside the pilot.  Often found in Battle of Britain Hurricane and Spitfire wrecks, these are highly collectable as well as forming an essential addition to a restoration or display.  The figures were usually engraved to suit the particular engine and application, but the boxes are BLANK in this case. These are NOT cheap screen printed reproductions but are etched and black printed in brass relief.

Merlin III Hurricane cockpit plate (pg1 pwr)

This is superb a real rarity , I could not work out why this plate was written in French so wrote to Rolls Royce to find out and trace the engine number.

Dear Graham,

This is an unusual one. Engine number 22315 was allocated as part of a batch of 75 Merlin III for Belgium (for Hurricanes) on order number 0/4930, contract No. T.9064. The contract was cancelled in May 1940 when Belgium was invaded. Engine 22315 was never built and its engine number was cancelled. It is likely that the cockpit plate may have been prepared (in French) because the engine had been allocated to the Belgian contract, but then upon cancellation the plate was withdrawn – and potentially taken as a souvenir. Part of that batch had already been despatched from Derby, but were recalled and intercepted at the docks. Of the 75 engines in the order, 61 were not built.

The De Havilland Hornet represents in many ways the peak of piston engine fighter design. With its slim fuselage, clean lines and tightly cowled engines, great attention was paid from the outset on maximising performance.


The prototype (RR915) was built on a private venture basis and flew for the first time on 28th July 1944.

Designed around the successful wooden construction principals of the De Havilland Mosquito, the Hornet was powered by a pair of 2,070 hp Merlin engines driving opposite-handed propellers and Boscombe Down trials revealed the astonishing maximum speed of 485 mph at 22,000 ft. The type also possessed superb handling characteristics, particularly in respect of its high rate of roll.

 

Initially conceived for operations in the Pacific Theatre against the Japanese, the conflict had ended before the aircraft reached operational status. Two main marks saw service with the RAF Fighter Command: The F Mk 1 and the F Mk 3 with the latter having increased fuel capacity and a large dorsal fin. Armament was four 20mm cannon and wing hard points eight ground attack rockets or a pair of 1,000 lb bombs. Alternatively, two 200 gallon drop tanks could be carried.

 

It saw active service in the Far East as a Strike Fighter during the Malayan Emergency in 1951, replacing Bristol Beaufighters and Supermarine Spitfires.

 

Merlin 131De Havilland Hornet engine plate (pg1 pwr)

This is a brass identification plate plate as fitted to the Merlin Mk 131 it is original and never fitted new old stock.

The Merlin 131 was a redesigned "slimline" versions for the De Haviland Hornet. The engine was modified to decrease frontal area to a minimum and was the first Merlin series to use down-draught induction systems. The two-speed, two-stage supercharger and S.U. injection carburettor giving a maximum boost of +25 psi . On the Hornet the Merlin 130 was fitted in the starboard nacelle the Merlin 131 fitted in the port nacelle, and was converted to a left-hand tractor engine using an additional idler gear in the reduction gear casing.

Rolls Royce Merlin thermostat (pg2 pwr)

Here is a Merlin thermostat as you might guess its quite a large piece. Approximately 12" long  with 2 1/2" pipe connections. I am not sure if this design was fitted to all aircraft with the Merlin, currently I can only find one drawing of it fitted to a P 51 Mustang. I have the manual for the MK XIV with the griffon and although you can see it in place its not quite the same design as might be expected. It has its internal parts but have no way to test if its working.

Griffon Exhaust stubs (pg1 pwr)

The successor of the great Merlin engine, the Rolls-Royce Griffon

Seen under the MK XIV Spitfire the first Mk of Spitfire to be fitted with the Griffon

Griffon development began in response to a request from the Fleet Air Arm of the Royal Navy in 1938. Navy aircraft tend to be larger and heavier than their land-based counterparts; this obviously puts greater demands on the engine if performance is to be maintained. To meet this demand, Rolls-Royce went back to the concept of the Schnider Air Racing Trophy “R” engine. The Griffon, essentially a modernized Merlin, is a 60 degree V-12 with 2239 cu. in. displacement (the same parameters as the “R” and 36% greater displacement than the Merlin while having an only slightly larger frontal area.) However, this was a totally new engine, featuring many design updates and improvements over the Merlin.

Merlin Con Rod (No 8 pg 1 PWR)

Here we have the Con Rod From a Rolls Royce Merlin Engine.

In a reciprocating piston engine, the connecting rod or conrod connects the piston to the crank or crankshaft. Together with the crank, they form a simple mechanism that converts reciprocating motion into rotating motion.

As a conrod is rigid, it may transmit either a push or a pull and so the rod may rotate the crank through both halves of a revolution, i.e. piston pushing and piston pulling.
