WW2 Prototypes

Fairey Fulmar N1854 is the prototype Mk II.

N1854 was the first Fulmar built and is considered to be the prototype.

The Sea Vampire at the FAAM Yeovilton.

Doesn’t at least a wing (or major part thereof) from the Stirling Prototype still exist at Orfordness?

No. We think this is from a Lancaster.

Two aircraft designed and contracted for during the war, but not flown until November, 1947 (an odd coincidence) survive:

The sole XC-99, the transport variant of the Convair B-36 bomber. It later saw service with the U.S. Air Force.

The sole Hughes H-4 flying boat. It’s better known by its unofficial and incorrect nickname, The Spruce Goose.

The XR-4 helicopter (RAF Hoverfly) is in the collection of the National Air and Space Museum. The type saw operational use in the Pacific and combat in Burma.
And on a related note, Igor Sikorsky’s proof of concept VS-300 also survives at the Henry Ford museum in Dearborn, Michigan.
It can be considered the prototype for the prototype R-4.

Another proof of concept aircraft, the first Bell 30 helicopter, also is owned by the NASM. With a first flown date of 29 Dec. 1942, it was the first Bell helicopter and essentially a prototype for what would become the Bell 47, the first helicopter in the world approved for commercial production and sale.

The second XP-82 Twin Mustang survives and it flies!

DH98 Mosquito prototype W4050 is at De Havilland Aircraft Museum at Salisbury Hall of course.

The second XP-55 42-78846 and second XP-56 42-38353 both survive
Horton Ho 229 V3
Bv155 V2

First prototype of the Ryan PT-22 is still around (at Old Warden?)

LA607 Hawker Tempest II second prototype (ex Cranfield and Skyfame Museum) is stored with Kermit Weeks collection in Florida.

Doesn’t at least a wing (or major part thereof) from the Stirling Prototype still exist at Orfordness?
