Which steam locos do these whistles belong to? (if any)

Hey, guys!

I've heard these beautiful whistles my entire life everywhere, but I don't know which locomotives these belong to.... I have attached a file, and a link to the video.
I really hope these are real whistles, because they are beautiful. Thank you for your time and help!

Many whistles were off-the-shelf models. A lot of railroads used one whistle for freight locos and another for passenger locos. Some engineers modified their whistles to make them "their own". You knew when he was coming to town. Some could be custom ordered. Both of your samples seem generic to me. Sweet sounding, of course.

Many engineers would "quill" their whistles. Not that it was a special sound, but HOW it was played. Running a steam loco during Christmas Express runs, I could quill the whistle into playing "Jingle Bells", at least the first 11 notes.

Some whistles might be famous. The whistle heard at the start of "The Flintstones" cartoon, a stock sound of Hanna-Barbera Productions, is the whistle from Ely-Thomas Lumber Co.'s Shay #6, located at the NJ Museum of Transportation's Pine Creek RR in New Jersey. http://www.njmt.org" onclick="window.open(this.href);return false;
