I have a few whistles available for immediate shipping. A good time to save a little cash, if you are in the USA, with the Canadian dollar at about 70 cents. As well, I plan to increase my prices by about 10% at the end of this month.
You can find a description of the whistles on my website, http://www.obrienwhistles.com
Thanks for looking. You can PM or email through the website, if you are interested.
