Unknown Sound Effects Library, Train Whistle 26

This is a rare sound effect that cannot be found on any (already known) sound effects library, and it is going to be placed in the Unknown Sound Effects Library.

The whistle that is heard in this sound effect is said to be Norfolk & Western #1218's or LMS Black 5's hooter whistles. However, it's possible that this whistle could've been from either a steamboat, steamship or a paddle steamer.
