FT: Burke composite for ?

I recently acquired an amazing Burke session bore high d composite made of Bakelite. It is very responsive and really lightweight, but I don’t think it’s the right whistle for me because I tend to overblow. I’d be interested in a trade for whistle(s) of equal value. I know these now go for two hundred dollars. This one Is 2 yrs. Old, so maybe worth $140 just a guess.
