It is an engine whose distinctive roar can make the heart leap.

The successor of the great Merlin engine, the Rolls Royce Griffon also played its part in helping to win the Second World War when it was fitted to iconic warbirds such as the Spitfire.

Now three excellent examples of the type are set to go under the hammer and sell for thousands of pounds.

The three 36.7 litre V12 engines were used in Supermarine Spitfires and the four-engined post-war Avro Shackleton - and are examples of the advanced technology which helped achieve superiority over the Germans.

Today just one Shackleton and fewer than 60 Spitfires originally fitted with one of these engines are still flying anywhere in the world.

And the majority of the left-over engines were disposed of after the War - some even tipped down a mine shaft just to get rid of them.

The mammoth engines were discovered in a barn in Derbyshire during a house call to see furniture and ‘some stuff in the shed’ and are expected to make more than 10,000 each.

Bamfords Auctioneer Steven Iredale said: 'These extremely rare pieces of British history have been saved from destruction for more than 30 years.

THE SOARING GRIFFON ENGINE

The Griffon was the last in the line of V-12 aero engines to be produced by Rolls-Royce with production ceasing in 1955.

Griffon engines remain in Royal Air Force service today with the Battle of Britain Memorial Flight and also power the last remaining airworthy Avro Shackleton - which flies in South Africa.

Rolls Royce

In line with Rolls-Royce convention the Griffon was named after a bird of prey, in this case the Griffon Vulture and was commissioned by the Fleet Air Arm as a larger, more powerful version of the Merlin engine for use in naval aircraft.

Although the Griffon was designed for naval aircraft, on 8 November 1939 N. E. Rowe of the Air Ministry suggested fitting the Griffon in a Supermarine Spitfire and this was achieved in 1941.

Spitfire XII's were the first recipient of the Griffon, a number of subsequent Spitfires retained Merlin power but towards the end of Spitfire production all were powered by Griffons.

Towards the end of the war Coastal Command found a need for a new land-based Maritime Reconnaissance aircraft culminating in Specification R5/46, which became the Avro Shackleton, a descendant of the Lincoln and Lancaster bombers, with four Griffon engines.

The Shackleton first flew in 1949 and the MK 1A Shackleton, with uprated Griffon 57A engines entered service with 120 Sqn. in April 1951. Production of the Griffon ceased in 1955 a total of 8,108 being built. 

'They were part of a collection belonging to Dan Taylor who has dedicated his life to the preservation and conservation of Vintage Aircraft.

'He had rescued these engines which he thought were of little worth as well as saving the original patterns for the legendary World War Two Merlin engine from a skip.

'While serving with the RAF he was involved in the making of the Dambusters movie, and almost every Spitfire still flying today owes something to his expertise - he is a real unsung hero of British military aviation history.

'The sale will also include his extensive collection of aircraft parts including propellers, an anti-gravity test rig and a Spitfire gun camera.

'It’s one of the most unusual and exciting sales we have ever handled and has already attracted worldwide interest.

'It’s something we have never dealt with before and even more unusual as we only went to see the furniture in his house and shed and came across these two and a half tonne nine foot giants.'

Other items that will excite aviation fans include a Stromberg injection carburetor which was part of a P51 Mustang engine.

The lots also include pistons believed to have come from a Merlin engine as well as 13 magneto generators that date from both world wars and some from the present day.

The three identical engines are Rolls Royce Griffon mk.58 V12s.

The 36.7 litre supercharged engines are capable of producing 1,960 horse power and are liquid-cooled.

One has no flying hours left and was removed from R.A.F. 8 Squadron Avro Shackleton maritime patrol aircraft WL745 1980.

Another has 62 flying hours remaining and was removed from R.A.F. 8 Squadron Avro Shackleton maritime patrol aircraft WL747 1980.

Both are mounted on wooden stands and are dated approximately 1952.

The collection will form part of Bamfords mammoth four-day Antique, Fine Art and Collectors’ Sale from 26-29 June.
