I snagged a Benjamen fire alarm Howler model SWP off eBay. It's 110VAC, and in fairly decent shape, even with the original manufacture sticker kind of cracked up and somewhat missing still attached.
I wired it up today for a test and was very pleasantly surprised to find out it works quite well dispite finding the metal contact plate has 2 decent magnet "stamps" in it from 50+ years of use. It sounds just like the Family Feud strike buzzer, same as my re-labled IBM 4031-2B whcih is a twin projector verson (round trumpet like projectors).
Here's a few pics to of it

All of my Benjamen vibratory horns, most of which are re-labled. From right to left starting at the back, the Howler, IBM 4031-2B (both 2nd generation horns), un-used 12VAC IBM 4032-1B (3rd generation surface mount), 12VAC IBM 4030-2 (3rd generation twin projector), and 12VAC Faraday Type 2 (1st generation single projector)
