Messer Quackers Duck Call

I designed this duck call as an experiment. It can be used with one or two reeds. The pieces are seperate for customization if needed.
Tuning the reedis a bit fiddly. I also need to work on getting the sound board right.
The barrel has two locations for tying it on a lanyard, up to preference.
The insert has a very small ring to prevent it from going into the barrel too far. It is supposed to be there.
The wedge can be tuned to the reed(s) used. Alternatively a piece of cork,or heavy foam could be used instead.
For the reed(s) I cut some plastic stencil material 15mm wide,
