Well boys,
It may be purely legal as many engineers on the D&RG and also the New Mexico Lumber Co., based at McPhee owned their own Bell of the whistle. The NML #4 that killed James J. Alley, of Alamosa had a 5 inch diameter Bell. They moved the Bell when assigned onto a different engine. The valve usually was untouched in the swap. Surely the engineers interest must have carried over to the engines in the scrap line or re route to one. Those crew men had a love for bells and whistles just as we do now. The moral of the story is to find them in the garage or under the trailer before they are trashed. But pay the owner (old widow) the fair price, like the auction price.
