1933 Horn Sound?

Dear Ford Friends,
I am restoring a 1933 Roadster and was wondering what the horn should sound like? For those that have a 33 Ford, does the horn have the Ahoogah sound (like the 28-31 Model As) or the beep sound? Thanks very much for your help.

At the three minute and 56 second mark in this video link below, they sound the horns. This is the correct sound for these horns. The two horns are adjusted to different tones from one another to get this correct sound when both are working in unison. I'm pretty sure the horns on both the '33 and '34 make the same sound....

The motor driven horns have the Klaxon or Ah-oo-gah sound. The small motor turns a ribbed disc in contact with the diaphragm to make the sound. The 1932 model year was the last of the Klaxon types for passenger cars. There were stragglers in the trucks for a year or two.

In 1933 they began using an electric ******** coil in contact with the diaphragm to make a solid tone report. Some are high pitch note and some are low pitch note to get a dual horn harmony sound. Many of the early V8 Fords were standard models and only had one horn. The Deluxe models had the dual horns.

PS: Dual horns have different ******** diaphragms for high and low notes. You can't adjust the pitch of the output tone but the harshness can be adjusted out for a more mellow quality.

Actually, the deluxe, 2nd right side horn when added on the 1933 and up cars/trucks, has a small cup shaped weight added to the diaphragm assembly to change the sound.
 
With respect, the ******** horn replaced the motor-driven horn on '32s about mid-model year, including commercial vehicles and big trucks.
 
So that's why the diaphragms were interchangeable from the 1932 model year. I learn something new all the time. I didn't figure it would interchange with a Klaxon type. Too much difference. I just know that I've seen 1932 cars with them.

There is a lot of info in the parts books but obviously not near enough info. They tend to reflect the changes and not the originally issued parts.
 
Thanks again -- any recommendations where I can find interior horn parts? I have checked Macs, Speedway, etc. and do not see any horn parts.
 
The centers (operating portions) of the two horns are basically the same through '37 and it may prove cost effective to find working versions of the later ones to replace what you have, retaining the bell, cover, and mounting bracket of your existing horn(s).
 
I expected the horns on the car in the video to make a good parp or loud beep sound. They sounded most peculiar to me. Is that really what they are supposed to sound like?

Hi all; For you fellows using 12 Volt and ******** horns... A RG 9 member just converted his '33 dual horns with High/low vibrators from HARBOR FREIGHT. They fit on the original plates and worked excellent.. even tunable! Newc
 
I have a post here on the barn showing a VW horn I fitted to an original spartan 34 horn. I think the beatle sound is close. Ken

I agree. It sounded sort of harsh or sickly to me. Some adjustment or service might be needed on that particular car.

I googled low and high vibrators :eek: but I couldn't find anything I could use in my horns...
 
He may be referring to the guts removed from a regular set of horns. The horns I see on the Harbor Freight site look to be the 12-volt types.

I've used guts from old Delco and Motorcraft horns to fix a few old ones before.

Got a link to that?
I'm very interested in updating a couple of Sparton horns for my 33. Actually, I only have one right now and its in sorry shape. I'm in the process of Delux-ifying my 33 Tudor Standard.
