Creative Playthings Resonator Whistle

“A permanent, plywood, glant-sized penny whistle, which we admit is a pretty penny. However, it is made for generations of use. A “pull out and push in” slide controls tone. A transparent plexiglas window reveals the air chamber and secret of all slide musical instruments. A child will work out tunes and create his own “penny whistle” jazz. A heritage toy, insured for use by generations of children and grand-children. Extra mouth pieces for the rest of the crowd.”
