Playing around in the shop with an idea for myself!! This Yelper has a Delrin press fit mouth piece & feral attached to the center barrel section of a yelper that has a delrin threaded insert on the end.

I made 2 different Turpin style bells with different internals and a Jordan style large section that I can screw onto the end of the call to change the sound and the looks of the call.
