Eric,
If you would like to hear some of your whistles we can do that at the Georgetown Loop. I am trying to arrange for someone with some good digital recording equipment to make a CD of all our whistles and everything we can borrow. We are in the process of borrowing some whistles from the Colorado RR Museum, one of which is a 5 chime step top marked #361. We operated our #40 at CRRM this weekend with a old 3 chime flat top with both CB&Q and C&S marking #905, which was a C&S 2-10-2. Beautiful whistle - everyone loved it. Let me know if you are interested in sounding some of your whistles at the Loop and making a CD.
