Commercial-type sales postings will not be allowed.

VIEWING MULTIPLE TOPICS ON SCREEN: You can choose to see more than 10 Topics at a time ... Log In and choose "Preferences" from the top bar on the Forum page. Scroll down and Change the "Default Topics Returned" parameter to 25 or 50, and save the changes. Since this setting is stored in your browser 'cookies' (if enabled), it seems to use that stored value even if you are not logged in. So, if you use a PC that you haven't logged into the forum from, the setting still seem to remain at the default.
EXTERNAL PHOTO LINKS ON FORUM: You can still use external photo links in your posts on the new forum. They follow the rules of any link in that they have to have the URL link qualified down to the full image file name (example: .jpg). The links will open in a new browser window, the same as an uploaded image attached to a post. Since an image attachment to any post does not display inline with the post, the results are the same. You can use multiple external links within a post. This link is from photos on a site from Don Clink's 'Deuce@75' albums:

Using links from photo sites such as Photobucket can help in "size" issue with uploaded attachment files. For best viewing in web browsers, photos should be around the 800x600 pixel range, and probably not more than 1024x768. Most cameras today store HUGE jpg image files, as the default settings are in the 7, 8, 10, and 12Mb image sizes. The image files that are then attached are very large, and the browser can't display the full image size without using the scroll bars. Use the re-sizing functions of your photo editing software to reduce the image to 800x600, which reduces the file sixe and the image load time in the browser. Don uses Google's free Picassa3 software, which is an excellent photo management product. All of the photo albums of the Deuce, Grand National, and Auburn that are links on the NORG site were built using Picassa's web creation functions. And it's free? (THANKS to Don Clink for the info!)

Would like to thank the helpful replies regarding the horns. Took the low horn contact assembly apart, removed the contact pitting as best I could using a fairly fine abrasive stone. Didn't move the armature as the GB shows two series of horn assemblies 13832-3 with different air gaps. Both the tiny cardboard sleeved insulators on the contact assembly were brittle, replaced them the insulating outer portions of wireless stakon (butt) connectors of the same dimension. Had quite a go reassembling but it works just fine, the high horn is tomorrow's turn. Hope the lengthy description helps someone else and thanks again. Gordon

What is wrong with your horns? Generally all that is required to make the horn itself work is cleaning the contact points.

The horns require quite a bit of current to operate and if there is no sound when the horn ring is pressed, the most common causes are a bad relay or poor grounding.

If the tone is off and they sound like a sick cow, the same causes apply.

To check the horn itself, connect a 12 gauge or thicker wire from the battery to the horn and then ground the horn by touching it to the body of the car.

The A suffix horns are 4.28" high and the B suffix horns are 4.14" high.

Dear'51;
They popped apart no problem, yet to decipher just which set I have. If I'm reading the GB correct there are two sets both having a high and low tone with each of the two sets having different gap measurements as well as different amperage. The amperage reading is the key as to which ones I have if I can get them working? thanks

Gordon. How did you make out with your horns? Did you get them singing a fine tune?

Appreciate the info, now that I got the round covers off without damaging anything I'll give the directions in the GB a go. Thanks for the interest in pics!

Gordon, Nice looking '51.
Any other photos you can show?
I have a '51 Hawthorne Green convert.
Is that the color of yours?
I can't get to it to check the horn but most of the
horns of that era operate in a similar fashion. So I guess they
would come apart the same way. Just go slow, line up the parts
as they come apart and take pictures.

Gordon. I don't know if the '51 horn is the same as or similar to the ones on my '46, but as I recall, (I'm old, and did the job a few years ago), the cover just snaps on to the body. I attached pics of what mine looks like inside. The problem was that one of the two horns was not working. It checked okay with the ohmmeter, so I cleaned the contacts with 1000 grit wet/dry paper and that fixed it. Hope this helps.
