Hi,
I'm from New Zealand and have a Heco Hand Operated Horn that is in good working condition that I would like some information on but cannot find any anywhere, it has a screw thread under the knob that you push down and it makes a rather loud ooohgar type noise. We wish to sell it but would like to know its approximate age. Its reasonably small so maybe also came off a motorbike. Any information would be appreciated.
Cheers
