I don’t know of any sample sources for this instrument: I just want to add that its name is “ghironda”, and it is a very interesting and strange instrument. Too bad that you sold it!
I know another older “world”-sounds collection. there are some Irish Hurdy-Gurdy sounds included but the Hurdy-Gurdy is an instrument with a huge number of percussive sounds and different tuning possibilities and so on … so much would be possible but the instrument is so less popular … it’s a pity
seems like that I must save some money, to buy a Hurdy-Grudy again … but a basic handmade Hurdy Gurdy (and there are only handmade ones) is as expensive as the Quantum Leap RA (ok a little more expensive ca. 1000 euro)
