Circa 2003. I got this when I was trying my hand at tin whistles. I didn’t go far with that, so my whistles haven’t gotten much use (I think I used my Hoover arrow the most). You can probably see some of my old posts here from around that time. I’m now trying my hand at ocarinas, so I decided to go ahead and sell at least one of my whistles. It’s in pretty good condition I think, hasn’t been used much, primarily collected dust 
See 3 photos here, and a (redacted) invoice for my original purchase.
Updated: $79 with shipping included (lower 48 states) [was $84]
