Ho takers. Well the engine a 200 H.P. Sunbeam Arab engine. The aircraft was intended for service with the Royal Navy.

Sopwith Cuckoo?

Not the Sopwith Cuckoo. However, it does have some connection to Sopwith

Hawker? He took over Sopwiths operation.

Not a Hawker

Grain Griffin?

That is the one. You have control

Ah - success! I have to admit to being intrigued by the Sunbeam Arab engine; it promised a great deal, but possibly a case of being slightly ahead of its time and/or technology?

OK so coming up-to-date a bit, this probably won't last long but I liked it the first time I saw it xxxxxx years ago:

Seems to be the result of a `3some` night of Ling-Temco,Fouga,and Fournier......

you forgot Bede......................

Bit of PZL,and add a dash of Williams,possibly a bit of Rutan,for the `veggies`....

Anything to do with Monnet?

Nope: it is American though. 1970s and a one-off.

Anyone...?

Still looking. Alreadt searched Janes 1973 through to 1981 without success, searched internet without luck. Closest aircraft meeting the image is the Fouga CM8 R9,8 - Cyclope I. However the aircraft in the challenge image is low swept wing and appears to be ac two seater.

It was indeed a two-seater, powered by a J85.

That will make it the Hammer-Hunt HH-1 Zipper. Very interesting challege.

Yay. A promising design with a sad story...
