Looking for some expertise on the whistles used on the D&S in recent years.
I rode the D&S Photo Special in 2003 with the "Bee" 473. She had a very beautiful chime whistle.
I then rode the Trains Unlimited special in 2005, with 473 (black) and she had a very mellow 3 or 4 chime.
Can anyone identify the origins and specifics of these whistles?
Thanks in advance.
