Attachment to forks

Does anyone know what the bit attached to the lower fork leg is? I have seen the same bit on a picture of the Stornello in the factory museum.

No idea but I’ll offer a go atA gear to change the speed of a speedo cable

I believe it’s a crude anti-theft device which is released with a key and the bar rotated into the wheel to stop it rotating. An early disc lock- without a disc!

Simon A has it right. Nice period accessory.

That would make sence, Could also be used as a spoke breaker when you forget it!Don’t think I will bother getting one for my Stornello
