Read here a while ago that the Big Boy, Challengers, and Northern all used the same 3 note Hancock whistle. Would like to know some dimensions OD, ID and overall length of the whistle and what the notes are. Planning to build one for 1-1/2" scale some time in the future but want an authentic sound. Can you all help? Thanks in advance, JD Johnson, Morehead and North Fork Railroad Historian |
