Here is my restored Sparton mechanical horn installed on my 1913 Runabout. It is a pretty rare one, instead of a push-down plunger, it has a lever that pushes forward and pulls back. It is very loud. I have a 1913 penny inlaid in the round knob for good luck ;)
sheesh, that is nice.
Gorgeous horn Ed! That is pretty shiny honker
My old rusty A-K-ORN brand horn works and fits well with Nellie.
A little added spring assist to the mechanism too
Here is the original magazine ad from 1916.
That’s an interesting one
Not mechanical but a "Combination Klaxon" horn that I recently picked up within walking distance of my home.
It's massive - Coke can included for comparison.
Talk about a rich man's toy! $50 in 1913 would be $1,259.28 today.
That would mean that a $500 car in 1913 would be equal to a $12,000 car today. Model T's would have been to expensive for the common folks.

Here's my honker :
This is the horn on my '10. Mounts on the steering column. Never saw another one like it. Plenty loud
Arnold, A new $12,000 car today is pretty much bottom-of-the line, isn't it? (I'm not in the market for a new car, so I don't really know)
A bit far away, but my 1915 pat. hand Klasonette is on the ?War Wagon. Extremely loud. It's a little hard to push and I leave it that way so it doesn't turn into the McDonalds Playhouse at shows and events.
It works when it neds to.
The Mighty Ahoogah
The visual impact of a Brass-Era automobile is so striking, it can overshadow the other senses, which is kind of a shame because the way these cars sound is also wonderfully unique, and everyone who works with them just loves the low-revving kisskisskisskiss sound of a flat-head engine. -Oh, but the horns! -I was surprised to learn that Klaxon horns had been marketed fairly early in the game—1908—which coincided with the earliest production of Henry Ford's Model T. -I had thought that those early days were the sole domain of the squeeze-bulb horn. -Not so.
Miller Reese Hutchinson invented the Ahoogah-horn and it was first marketed by the Lovell-McConnell Manufacturing Co., the founder of which named the device, "Klaxon," a slight bastardization of "klazo," which, translated from Ancient Greek, means, "I shriek." -The first units were electric and later models, like the "Klaxonette," were hand-powered, but either type gets its characteristic ahoogah sound from a spinning cog that beats its rounded-off teeth against a rivet in the center of a metal diaphragm.
It was good to learn that these horns are period-correct for fairly early horseless-carriages because... well, I've always felt a little like it was cheating to have a hand-Klaxon instead of a squeeze-bulbed Mr. Magoo horn on my '15 Ford. -My defense for the compromise with historical accuracy had been a pretty weak excuse—simply that car-show spectators loved the sound of darned thing and expected antique cars to have them. -It also happens that the distinctive sound of these little beauties is so loudly raucous and attention-getting that from a safety standpoint, they're a good thing to have in busy traffic.
Steve Jelf, did you ever find a replacement handle for your mechanical horn?
Here is the Garford horn that is on my 1916 Touring car. It is easy to use because of the angle of the plunger. Sure is loud.
That's mine - unfortunately without branding.
This horn was on my grandfather's 1913 T. Here it is on his car in 1957, and now it's on my '15 T. It's called a Handphone. It has a great deep tone to it.Horn bell is nickel plated.
Just as a side note, my steering wheel in the above photo came off of this T. It was my great grandfather's. Photo from 1925. My grandma is sitting on the hood. This steering wheel was used for many years as a bird cage stand base for their canary.
Here is mine, painted some kind of military Gray.
