A Burke narrow bore aluminum D whistle in new condition.
This one has a thumbhole, which is pretty helpful and
not hard to learn to use. If you don't want to use it,
though, a piece of scotch tape over it and the
whistle plays as if it wasn't there.
This comes with a lovely nylon sort of case. 150 shipping included,
CONUS.
