Nice that people are still playing crumhorns. The closest I came was the EMS Glastonbury Pipe, which was in my keeping circa 1983-92 and now resides in the instrumentarium of Misericordia (though without the stash of charas gold-seal I used to keep in the resonator). Listening to a live Amazing Blondel CD (Corner of a Foreign Field...) that turned up recently I'm sorely tempted to seek one out.

I wonder, do they still make those plastic / ABS ones??
