Sydney A. Holloway apparently designed the SAH 1 after building a flying model Pup in metal. Alan Greenhalgh (One time Beagle designer and very much involved in the Pup) always called the SAH 1 "a reworked Pup." The T67 was originally ex. Fournier ( French) and the USAF experience with the type has been covered on other threads by those with qualified opinions.
