Identify a Horn?

[djlanier]

Found some auto horns in a box of parts. Can anyone tell me what they are for? No numbers or letters on the horns to help ID.

That looks to me to be the rare Triangular-bell horn that was used on several different makes and models of cars, depending on which mounting bracket was used.

Thanks. I have 6 or 7 and they do seem to have a variety of mounting brackets.
