My Dad has asked me to post a request for anybody who has built a successful working 3 to 5 chime whistle. If so could they supply drawings, info, or a “how to do it” He is looking at a whistle of no more than 2 to 2 1/2 inch’s tall as he wishes to put it on his loco where it will be seen. Any help greatfully recieved.
Many thanks for the info, appoligies for not posting earlier. Should have used my database better & would have found the refence to the article you mentioned!
