Hello
I have a Howard low D whistle that just doesn’t suit me. It’s the black type, about two years old, complete with its plastic box. Hardly played. Anyone fancy doing a swop for another whistle of roughly equivalent value? Any key except high D. I’d rather trade it than sell it. No point in ending up with fewer whistles than I already have. 
Send me a PM if you’re interested. (I’m in England, by the way)
