Anyone interested in having some fun and play: Guess what that whistle is…? Just curious to sample what you might guess the mystery whistle is. Here a sound bite of By Yon Sally Gardens, played with a C whistle…

No sound processing what-so-ever, plain cheap mic recording.
First clue… you don’t have to wait months to get this one…
Any guess?

Sounds somewhat plastic-like. Maybe a Susato. It kind of sounds like one of the ones I’ve made out of PVC.
or…its the one that your thinking of, that I know, just refuse to tell. 
I will definitely tell what it is, not hiding anything, I am just thinking that it’ll be fun to try to guess.
Second clue: not home made, widely available commercially.
I’m guessing Clarke or Shaw, because it has a little wind and sounds like thin metal. But on the other hand, it doesn’t sound conical, so I’m not too sure.
It didn’t seem to sound like a Susato on the high notes to me. I don’t know what it does sound like though. 
I was going to guess a Jerry Tweaked Shaw.
Oh, this is interesting.
I agree with O’Brien. It sounds like thin metal and not conical.
I do tweaked Shaws in C, but there aren’t a lot of them out there. The timbre is more complex somehow, on a tweaked Shaw, due to a combination of the mouthpiece configuration and a certain kind of resonance from the conical construction, and the bell note is stronger on a tweaked Shaw.
But what that whistle is, I really have no idea at all.
Best wishes,
Jerry
Probably a Sweetone.
I’ll have to retract the vote for not conical.
I think Avery may be right. I pulled out a C Sweetone, and it sounds very much like that.
Best wishes,
Jerry
Is it a Clarke Original?
I’m very confident that it isn’t a Susato or a Hoover. I also don’t think it’s a Feadog. Doesn’t sound like my silver Generation.
I agree that it’s very like a Sweetone. But because knowledgeable folks have already voted for that, I’m voting Walton’s Mellow D on the chance that I could win the contest because I’m the first to guess this.
Clarke Original.
All pretty good responses. The closest educated guess goes to the sweetone votes; close enough.
It is a MEG.
I found that it was a great way of describing unbiased characteristic of a given whistle. Should have have more rounds of this game?
Roger
In complete honesty, I was thinking about that tune earlier, and I was thinking about it being a Meg.
Why not? It was enjoyable and interesting.
Cool I was the first to guess a Sweetone and i was almost right. 
can I have a go?
OK, I’ll go with the first guess as I started this…
I feel some backpressure, I am guessing a copper base whistle, but seems to be too much chiff for an O’Brien. Not plastic base, I am pretty confident, definitely not Susato. I haven’t heard many clips of Serpent whistles, and dont’ have one myself, but I’ll open the vote with Serpent as a first guess…
Roger
I’m going to guess something made out of wood. Don’t laugh too hard. I’ve only tried 3 whistles in my life.
It is much breathier than any of mine. I have never played a Serpent but I understand they are pretty breathy, could be. It might be a Shaw but the only one I have played didn’t seem to be that breathy.
