Vickers Jockey - The Vickers Type 151 Jockey was an experimental low-wing monoplane interceptor fighter powered by a radial engine. It was later modified into the Type 171 Jockey II which had a more powerful engine and detailed improvements. Only one was built and this was lost before its development was complete but the knowledge gained enabled Vickers to produce the more refined Venom.
