Hello,
Does anyone know where I get get my hands on Pat O Riodans wooden tin whistle in C or can anyone point me to another whistle that sounds similar, it would be much appreciated have looked for one for years!
Pat O’Riordan Whistles are as common as hen’s teeth,good luck with the hunt.
On the bright side McManus makes a great wooden “C” whistle.
Did you see this?

Nina,
As was stated Pat’s whistles are hard to find. More rare yet, the elusive “wooden tin whistle”. Ye will be hard pressed to find one, t’is wood or metal lass, ye can’t have it both ways. 
All joking aside, I have one of Pat’s whistles in G, fantastic maker. 
Good luck with ye search and save ye pennies, t’is not a penny whistle.
Cheers,
Cayden
To split more hairs, most wooden whistles have some metal. Those in the Abell/Schultz tradition, like Paul’s and mine, have metal mouthpieces, rings, and slides, and even Swayne’s and Bleazey’s, which have wooden mouthpieces, have metal rings and slides.
And I have yet to see a whistle actually made out of tin, which is really, REALLY soft. Like, when you put your lips on it soft.
How 'bout that Lady Huskies basketball team?
Don’t know how similar these are to Pat’s or any others, but you may want to have a look at Sweetheart whistles.
The Sweethearts are very nice, but not similar to O’Riordans.
The only whistles that I know of similar to Pat O’Riordan’s work are David Boisvert’s Greenwood whistles. His mouthpieces, nearly identical in design, are made of wood whereas Pat’s are of a ‘food-grade’ material (acetyl?) as he once wrote to me. I’ve owned a few of Boisvert’s whistles over the years and they are beautiful work.
