OK. So, I have this old Desmo brass (painted black) bulb horn that is 7″ long by 3-1/2″ at the honk end with good mesh. Overall with the bulb (cracked but works) and the extension, it is 19-1/2″ long. It has a few minor dents in the body, but is in good nick for a very old horn.
I want a much smaller bulb horn to clamp down the side of my TT Rep. If anyone wants to do a swap let me know ; it needs to be an old one though.
Of course, I could simply unscrew the extension piece and fit a smaller bulb, but 3-1/2″ diameter (at the honk end) is a bit over stated for me.
Might look very nice on the handelbar of an older model though.
