Old as dirt built to last it still worx check out the video of it up against my buffing wheel. I don' tknow where it mounts on a bike. I am still kind of awestruck that this is how it was done back in the day. don't bother calling me to complain about missing or incorrect parts. Can't be many of these out there and I want 400 for it. Click here http://werule.com/images/hdsiren.MOV to see it working. in case you didn't know(as I didn't) this thing rubs on the tire of the police cruiser you step on a pedal or a lever to a cable I don't know exactly ...
let me know if this interests you or you got questions
