I am not surprised that the University couldn't identify which apple it was. I suppose the same thing happened in the USA as happened in England about 80 to 150 years ago. Here, every keen gardener was trying to develope their own variety of apple. In a village near where I live, a local man evolved a very popular apple. His name was Stallybrass so the apple got called the Stallybrass Wonder. Do any exist today, possibly, but who would know the name and be able to identify the apple.
