Copper F# Short Pentatonic Whistle

Condition: Excellent/As-New

Play a 5-note scale starting on F# (all holes covered).  Covering hole 1 yields the first octave up.  Seems to be meant to play just within about 1-octave.  Notes are:

F#, G#, B, C#, D#, F#.

Never have seen a whistle like this.  Not sure if this was a DIY make or an established maker.  The tone is very whispy and not focussed.  More of a conversation piece than anything else!
