Hello as most I have listened to the whistles and wished I could take one home and blow it on air. Well now I can in a way a friend of mine makes somewhat repos of 6" whistles so if you have a pic and the dimentions you can have one built for about 350-450$. If you want one call Mike at1-304-367-1765 6-10pm eastern he is in WV. thanks Matt Ritchie Tulsa OK
