Another HORN question

[Kahuna]

I have an Ahooga horn. It works OK.
I don't know what it's from? It has NO bell on the front.
someone once mentioned it came from a truck.
I can post a picture tomorrow
Any ideas?
Thanks
Jim

KLAXON made ahooga (motor driven) horns for GM cars. My 29 Chevy has one with a slight taper on the trumpet, but no bell mouth on the end like the Model A.

Check the bottom of the motor mounting rim for identification stamps;

Here are some motor types;

Recessed screws, Sparton
The other is Stewart Warner

Some are very faint. Carefully remove the paint with liquid paint remover to reveal the imprinting. Then match it with Mike's examples.

Did the model A's ever come with a Stewart Warner horn?

When I bought my 30 Briggs Town sedan, it had a Stewart Warner horn, that always sounded weak and sluggish.

Yes, in fact that might be the most common brand. Look closely around the flange for a name that is lightly stamped in.

Tom: Yes, it is stamped in script. "Stewart Warner". "Made in U S A" , so, that likely was the original, "correct" horn for this car.

I notice the brushes are much smaller, in fact the entire motor is smaller, than the Sparton horn I just installed.

I am hoping I can get this one working strong again.

Thank you for the guidance, Tom. I really appreciate your response.

Thank You.

Can you post a picture of the Stewart horn?
They shouldn't be much different than the Sparton as far as size and sound.

The SW horn I restored for Dads car last summer has a very nice sound. I almost swapped horns with him as it is slightly louder than my Ames. Guesse I will see how the 2 Spartons that are on the bench sound before I make a decesion on which one to keep. Rod

Tom:

I notice the brushes are smaller, the armature is smaller, the field coils are smaller, and have extensions.

Does this horn look like an original?

Thank You

Mike; thank you, that was very informative.

Thank You.

A recurring enlightenment whenever Stewart Warner horns are discussed is, the screw holding the waved vibrator disc to the armature is LEFT HAND THREAD. Don't twist it off!!

[Brianfrench65]

So.....if Stewart Warner horns were standard equipment for Ford, when did the Sparton horn come into use? Was it just sold as a replacement horn? Did the dirt roads beat the horns up to the point, you needed to replace them?

Just curious, and trying to learn.

Thank You.

They were one of 5 manufacturers Ford used during production. Most all at the same time. See the Judging Standards for changes and time line. Rod
