Very impressive collection, Geoff! My sister's ex-husband was a guitar teacher and two or three walls of their lounge were strung with various guitars and basses. Don't think he had one of these though.
As a fellow musician (organ, piano and keyboards) I know just how attached we can get to our 'babies'. Thing is, I have friends who collect organs like you collect guitars and they take up just a
little more floor space! I think the current 'high score' is 13 organs in one house - he has a very understanding (or just simply resigned to it) wife!
