What is it ? Answers on a postcard

[cheshiremorris]

Sorry to fill the forum up with trivial things but I appear to have a football shaped thing in the boot which I have no idea what it is. One side looks like the output part of a horn but its 5 times bigger than any horn Ive ever seen, guess it could be a powerful classic horn to beep at the porsche drivers as you zoom past them [frame][/frame]

it is an early horn. would not be wanting to sit in the car with that going of behind me.. might be an early attempt at a car alarm.

Looks like a Lucas windtone horn.
They were manufactured in two types - high note and low note and were frequently mounted at the front of the car in the open for best sound.

Lucas Windtone horn. If you look just inside the mouth it should be stamped H or L, for best results they should be fitted in pairs[frame][/frame][frame][/frame]

I bought one of these at an autojumble last year - but all I can get from it is a miserable 'croak' - anyone know how to make it sound properly?

[graham1957]

the bracket on a horn is usually laminated, ie several thin layers of bracket .in my experience if this bracket is omitted the horn will sound dull and a bit on the quiet side, also a clean and adjustment can improve them

[bmcecosse]

YES! It does have a laminated bracket - and it's broken.....and I did wonder how that would affect the sound. I guess the whole horn has to 'resonate' to make a 'good' noise. I'll have a think about how to fix that - but I suspect it will be spring steel.........

I had a set of these fitted in the engine bay of my Metro GTi - frightened the crap out of unsuspecting boy racers!

Not 100% sure but I think there is an adjusting screw,on them ,to get them to work at diferent intensities,so may be a bit of a fiddle will produce a sound,rather than a croak,think its a bit like adjusting the overthrow on a pump.In fact in the photo is that it on the dome

[mike.perry]

Remove the dome and there is an adjusting screw inside. For further reading see Taffthehorns.com website

I tried the screw when I bought it - but still to read the pdf.....
