Does anyone have an illustration of the evolution of electric horns? I have been trying to find a picture of the battery horn used on a 1923 T.
All I can find are pictures of the magneto horn with either a firewall bracket or head bolt bracket .. or a battery horn on a head bolt bracket and the water inlet bracket. And every picture of the battery horn on the water inlet bracket is listed as 1926-27.
So are all the battery horns the same and it's just the bracket that changed from 1923-1927?
Just observations from battery horns have seen.
The electric horn, vibrator diaphragm type, are found with Ames mfg. stamps (no script), and with Ford script stamps. The Ford script ones also have the cover stamped Made in USA, and with a diamond shape stamp, which is likely the supplier of the most found script electric horns.
This battery horn was used in 1922 with a special 'z' bracket on the firewall, like the magneto horn too.
Maybe the Ames is the earlier, as the bracket is mounted with 2 rivets and one stove bolt. The Ford script has the brackets held with 3 stove bolts, most have the nuts cross staked to keep them in place.
So in 1926 the new water outlet bracket could be used on the horn, as the 3 stove bolts are used to mount the bracket also.

Have you checked Bruce's encyclopedia? Pages 530-535.
I don't have a copy of Bruce's Encyclopedia .. sounds interesting. Where does one find it?
