Identification help requested.

[Malcolm Clarke]

This is an extract from a photo passed on to me and I am trying to identify the two aircraft shown - apologies for the poor quality. My belief is that it was taken in the 1930's.
The RH aircraft appears, from the fuselage mounted rotor supports, to be a Cierva auto giro but has a four bladed rotor rather than the three blades usually found.
The LH aircraft has the appearance of a flying wing, with winglets & out-riggers. The shape of what could possibly a be a rear fuselage? is difficult to determine.
Both have RAF roundels.
I don't think the blob in the sky has any significance!
Can anyone help with their identities please?

Malcolm.

The one on the left is one of the versions of the Westland Hill Pterodactyl. There were glider and powered models but it's difficult to see which model it is.

The one on the right could be a Cierva C6 also made as the Avro 574. It definitely had a four blade rotor but may be a tad early and I have never seen a photo of one in with RAF roundels, only Spanish ones.

Many thanks for the responses.

Having looked at many images on the Internet, I feel certain that you are correct about the Pterodactyl. The Image is too indistinct to be able to tie down the variant

Regarding the autogiro, I had thought that the airfield is in the UK, and although the Spanish roundals are much like the British in B & W, not sure what a Spanish aircraft would be over here for. Also, the rotor supports on the C6 are quite slender, those in the photo look sturdier but then the image very poor in respect of detail.

From their uniforms, what nationality are the service men?
