You should visit the Byerly Road Railroad Crossing north of Boring, MD. It has a unique bell-only signal with a crossbuck. No lights or gates, just a bell.
The siren you showed in the video is a Federal "Type Mach. B", manufactured by a company called "Federal Sign Systems", or Federal Electric Company (now known as Federal Signal). It is a slightly older design than the M, the style you documented being made between 1917 and 1922. These have really tiny fans with tiny vanes and have a rather pathetic sound output, and they didn't make an insane amount of sales in their day. Or if they did, they all got swapped out pretty early, making it a fairly rare find nowadays. That one is missing the impeller though, rendering it completely inoperable.
