Gosh, we really did tread the same ground, atb1943. The Knight Twisters! They used to be in the HAC clubroom, as I recall. Last I heard they were in a shed at Biggin, which would figure because the owner was one C J de Vere, and I assume this to be the same Chris de Vere who ran a charter company (Interflight?) out of Biggin with an elderly Aero Commander 520 that was wrecked (on the ground) in one of the great storms.
