Help mounting vintage noise making accessory ?

[mofoco1]

Can anyone help with the mounting of this accessory. It's a vintage noise maker or siren that i assume mounts the either the front lg of the forks or the rear drop legs. The link at the bottom of the page almost is it. Thanks...Mo in CA

"No real trick to it really. Some run on the side of the tire, some on the top. Just clamp it to the fork so that it makes good contact with the tire and run a chain or string to the handlebar from the pull tab. Joel "
