Hurricane vs. Mobil Directo - SirenCon 2023 Finale
An ACA Hurricane MKII and a B&N Mobil Directo (BN52, gas powered) sirens compete during the final soundoff at Sirencon 2023. Both ex-Milwaukee units, the Directo was in service during World War II and the Hurricane was in service until its replacement 20 or so years ago; it had not sounded since its removal until the event.
The Mobil Directo won this contest, hands down. Enjoy!
