This gentleman is a Scottish busker living in Galway. He says his instrument a combination of strings and a handle you wind is Hurdy Gurdy.
For the record he was playing My Bonnie while I took his picture...
My hubby made a hurdy gurdy (see Feb 8th for pic). I do find them a remarkably strange instrument - the sound they make is somewhat of an acquired taste! :))
