im visiting there on sunday 
thought it would be nice if theres such a thing there…
even a place where you can get just cheap ones ?
yes there is a shop in the centre of amsterdam on the SPUI ( streetname) which sells whistles…I believe the name is berkel music see www.berkelmusic.nl website also in english and they sell clarke sweetones, generations and kerry whistles.
greetings

Sorry for the correction … not that it really matters, but I think that websites should be http://www.berkelmuziek.nl. Have a lot of fun in Amsterdam Eran!
oh dear that is what happens when you mail so early in the morning
