In todays video we mess with something I really have wanted to for a while but never had the opportunity to pull one apart I don't know what year this whistle is from how ever it is a 3" single chime hooter I believe it was either a shop whistle or on a locomotive at some point.
Big thank you to my friends Bryan and Nate for the help with the whistle as well as the information they have shared about steam whistles/ engines in general.
