For anyone who’s interested, I just put my mint-condition Pat O’Riordan African blackwood high D concert whistle on eBay as item #7321236542.
If you have any questions about the whistle, please send them via eBay, rather than responding here.
Where, oh where, does the Reserve reside on this whistle??? 
The auction will have a winner - auction is at $350!
Sold for $661.00 !!!
I’ll bet even Pat thinks this is a ridiculous amount to pay for a used whistle.

I’ll bet even Pat thinks this is a ridiculous amount to pay for a used whistle.
I bet he’s flattered. I certainly would be.
I just wanted to take this time to say “I told you so” to all the folks who kept telling me different when I said these whistles often sell for $600-700 on ebay 
I spoke to Pat a few months ago. I can’t remember exactly what about (a low D I believe), but the subject of an auction involving a C/D Traveler set came up. He told me “You are not going to pay THAT much for those whistles, are you?” At the time the bids were about $500 and climbed to $610 before it all ended.
I think Pat believes those who would pay that much for his work are NUTS!!!
