As an habitual collector of anything vaguely musical, I fully empathise!!

At last count I had something like 20 guitars, 2 electric basses, dozens of whistles and recorders, 2 Boehm flutes, an alto sax, a fiddle, a lap dulcimer (Stefan Sobell!), a piano, a Selmer Clavioline 'Concert', a Hohner Pianet (not 'Planet'!!), 2 electronic keyboards, 5 piano accordions, 5 melodeons, 3 English concertinas, 4 Anglo concertinas, a 'harmonium' (well, really an 'American Organ' by Bell, Ontario - they suck, harmoniums blow), and other stuff I'll probably remember next time I trip over them!

I hasten to add, not all of these are in fully playable condition, but I'm getting a round toowit... eventually...
