The area of damage is marked out ready for removing and replacing. Damaged area cut out and removed, exposing some of the internal structure of the blenheim. And the area after a section of aluminium skinning is let in, replacing the damaged skin on the blenheim fuselage. It just needs zinc etch priming and the rivet heads filled.

Dave, has nearly painted the inside of the fuselage over the last two days. The museum volunteers swooped the fuselage and centre section around today. They also rolled the centre section over onto its belly, so everything is ready for painting tomorrow.

Dave  and  Julian (right) comparing the Blenheim camo drawings to the newly sprayed fuselage. Dave had masked out all the areas of the centre section of the Blenheim so that Julian could crack straight on and paint it. A short time later Julian had the the centre section sprayed. As soon as the paint had been baked on the fuselage it was a case of juggle the hangar to get the centre section into the spray booth and the fuselage further into the Stuart-Buttle Memorial Hangar. And here is the fuselage of the Bristol Blenheim Mk.IV in all her glory and camouflage! Friday, 17 February, the volunteers did a dummy run at laying the Blenheim out in the car park today in preparation for tomorrow's 'Meet the Blenheim Project Day' In preparation for tomorrow's 'Meet the Blenheim Project Day' 23 February, Dave and Brad dummy assembled the undercarriage and engine mounts on the port side of the centre section.

The Blenheim Project

Bringing a Blenheim back to Hawkinge.

The Museum displays many of the aircraft types flown during the Battle of Britain, including Hurricanes, Spitfires, Messerschmitt Bf 109Es, a Defiant, Harvard, Tiger Moth and Magister. Original Battle of Britain aircraft are so rare, and so valuable, that the Hurricanes, Spitfires, Messerschmitt Bf 109s and Defiant are mostly replicas, though heavily rebuilt using many original parts.

Why the Blenheim Matters

One aircraft was missing from our line-up of Royal Air Force Fighter Command machines of the Battle of Britain period: the Bristol Blenheim.

The Blenheim in brief:

  • Of the 2,938 airmen awarded the Battle of Britain ‘clasp’, and therefore classed as one of ‘The Few’, nearly 800 flew in Blenheims during the Battle.
  • During 1940 it flew not only with Fighter Command but also with Bomber, Coastal and Training Commands.
  • In 1937 it became the RAF’s first all-metal monocoque monoplane and was the fastest aircraft on the inventory.
  • It was still the Service’s fastest bomber at the outbreak of the Second World War.

Four Airframes into One

The volunteers were therefore very pleased, and extremely excited, to acquire an example in November 2017: the substantial remains of four Bristol Bolingbrokes (Canadian-built Blenheims), to be rebuilt into one original airframe and displayed as a Bristol Blenheim Mk. IV.

Most of the project, including a fuselage, centre section and a pair of wings, arrived at the Museum in December 2017, with the cockpit section due to follow from Canada in the spring of 2018.

To help us complete the project we acquired the parts left over from the gorgeous Bristol Blenheim Mk. I (the short-nose version) rebuilt and flown by Aircraft Restorations Co. at Duxford. The trustees and volunteers extend their sincere thanks to John Romain, James Gilmour and all the team at Aircraft Restorations Co., who have been instrumental in turning our dreams into reality.

A Promise Kept

The Blenheim marks the end of a quest of nearly forty years by the Museum Chairman, Dave Brocklehurst, to bring one back to the former RAF Hawkinge, an airfield Blenheims operated from during 1940.

Dave would often ‘bicker’ with Mike Llewellyn, the late Founder and Curator of the Museum, that one day we would have a Boulton Paul Defiant and a Bristol Blenheim on display. Mike said this would never happen! We acquired the beautiful Boulton Paul Defiant replica, built by the Boulton Paul Association, in February 2015. We hope Mike is looking down, from wherever he might be, to see the promise Dave made to him coming to fruition.
