chaza87 you are correct. I have made the corrections and submitted them for update.

Thanks for keeping me honest.

Thank you for your comments re the individuals in the image. That is not C G Pullin in the picture. If you compare any of the characters in the picture with that of Pullin none fit the bill. From your references and images in your own publications you will see that none of the characters fit this description as you have said. The picture shows Maurice Brennan and no other. R A Pullin had a handle bar moustache when he was capture by the Germans. Though my main source was Neil Morris who knew them all personally. There is a splendid picture of Maurice Brennan in the Secret World of Vickers Guided Weapons, John Forbat, isbn 0752453165 page 67

I’ll check again.

Thank you.

Thank you for your comments.

I’m afraid your recognition of the various members of the Weir design team is off. The various individuals are correctly named, verified by myself with several cross checks and also by David Gibbings, former Rotodyne flight test engineer.

That’s a fabulous paper. I’m afraid the names of the design team of the W5 are slightly out. Yes Bennett is there but Raymond Pullin is on the extreme right. Maurice Brennan is the smallest figure. He went on to Cierva post – war and was involved with Saunders-Roe in the rocket programmes as well as helicopter work. There is a much fuller explanation of the Weir/Cierva development in the Sycamore Seeds ISBN-13: 978-0957344334. The appendix has a full list of patents, NARA and RAE reports on helicopter development and autogiro test work.
The figures in the group photo were pointed out to me by Neil Morris of H. Morris & Co which made the blades for all the Weir/ Cierva companies including the W9 and Cierva Air Horse. All the blades they made were wooden

Thanks for that ….as well as the serious aero-engineering there are several photos from Hanworth and nearby Hounslow Heath
