Hi,

Houston Gyroplane Projected single seat gyroplane designed by P.J.Houston as an advance on similar contemporary types. It was to have been constructed at South Nutfield, Surrey and the registration
G-ARSZ was allocated to the designer in September 1961, but the scheme was eventually shelved.

Derek Penn-Smith's autogyro was preserved - at least until recently. It was in the collection the now-shuttered Stondon Transport Museum at Henlow. In 2015 the autogyro was auctioned off by Brightwells with an estimated value of £600. Quote below come from the auction bumf:

"There was only one aircraft built: G-AXOM and this was first flown at Wymeswold airfield on 5th April 1970. The Penn-Smith gyrocopter made its first public appearance (non-flying) at Sywell aerodrome on 11th July 1970 and a Permit to Fly (a type of certificate of airworthiness) was issued on 25th August 1970... Retired from use in 1974, G-AXOM was aquired for the Stondon Collection in 1994."

That could be J.A.J. Bennett (James Allan Jamieson Bennett). Perhaps a follow-on from his 1944 US Patent - US 2,344,967 'Helicopters and Gyroplanes' - and his British application 32,731 dated November 26, 1937?


The 1944 US patent (applied for in 1937) is better-known because it featured in a suit brought against Kaman in 1967 for infringement by the latter's HOK-1 design.

Cases Decided in the United States Court of Claims: October 1, 1967, to December 31, 1967, Volume CLXXXI, by United States Court of Claims, Margaret Hunter Pierce, pp 158-161
