well, occasionally

ukelin,
1900 Zimmerman autoharp with 'shifters',
ceramic ocarinas,
nose flute,

whistles made of stall warning devices for small airplanes..bags & bags of'em(small reeds..set in pink plastic)..each has it's own basic tone, but you can 'lip them up' getting 3-4 notes from each..I guess I have maybe 20,000 to experiment with
