I was just searching through some old photos on my hard drive and found this one of an old bicycle "siren" I used to own.
I think they were actually called "sqwakers" or "growlers" or something like that...this "
Red Baron" version was really bitchin' I wish I still had it but I sold it on Flea-Bay years ago :facepalm:
Would have really looked bada$$ on the handlebars of my Powerdyne Rail....
