HW: Might you recall the name of the Miller album - - - I did a quick Youtube search, and couldn't find it, by topic. Youtube is loaded with all kinds of recordings.
Guess we're seeing a lot of whistle swapping these days; Milw 261, I understand, is carryimg a Santa Fe 2900 whistle. I really liked the original Milw whistle, which sounded like a crazy woman, but the SF whistle probably scares the "rubes" off the tracks.
In stumbling around Youtube, bumped into this piece, with marvelous photos and a sampling of sound recordings, from a fellow named Wm. Spicer, of B&O, NYC and Pennsy steam. Neat autos, too! Take a peak! https://www.youtube.com/watch?v=mYj-6fKUGFM
