Hi Craig. Sorry I looked and have no pictures that would verify the type of paint under the plaque, nor do I have any recollection.

The paint I put on the trumpets is called Dupli-Color, Model MC200.

If you don't have a narrow putty knife, make one from a butter knife. Don't use a razor blade becasue the plaque is thin and you might damage it. john
John, the pieces for the compressor body and trumpet bases are nicely stripped. What process did you use for this? Any tips?

How did you heat the top cap to soften the adhesive? Oven? Propane? electric heat gun?

Please advise us on what silver and black paint and technique you use for the horn pieces.

Hi Craig,

I used Jasco paint remover, then a light blow in the blaster. Paint and primer stick like crazy glue to freshly blasted surfaces. The armature and the exciter need to come out of the compressor. A tight wrinkle finish requires heat and personally wouldn't subject 50 year old shellac to heat or dust. I’d use orange oil (or the like) to clean the armature and the exciter. Orange oil is not really so much oil in that it doesn’t leave oily residue. It’s more of a cleaner but it’s a gentle cleaner.

The gray hammer tone paint came from Orchard Supply Hardware and unlike the wrinkle paint, there is no fuss with applying it.

To remove the plaque heat it from the underside on a burner at a mild simmer setting then it’s feel and go.

Question: how do you guys substitute the washer that is under the compressor cap?

John - I tried babelfish.com but couldn't come up with a translation for armature and exciter. Which parts are these?

Hi Tom,

Sorry. The rotating part is the armature and the excitation field is the coil of wires around the armature. If you look at my picture on Page 6 of the exploded horn assembly you'll see them in the lower left.

Got it. Thanks! I am certainly learning more about horns than I ever thought I would.

Well, on the other hand, some might read this thread and think "boy, these guys need to get a life". :wink:

John,

I see your point! I have been accused of spending too much
time on this site. "Oh, so you're back on that Ferrari site
again already"?, is the common venacular. Hey, it's what
I enjoy doing, so be it.

The fun lies in the details. Anybody can buy an old car and run it as it is. Researching the history and making everything right is what makes this a hobby and a fun one at that. My business partner thinks I am over the top with this hobby, but then I ask him about his wine collection...

The blue trumpets were shown on the standard boxes of that early era as well, and may well be how the new series was introduced. I thought you had posted a picture of these trumpets, but i cant find it.
thanks

I finally got to the storage unit. Here is the photo of the compressor top on the 69 365 GT 2+2 to go with the horn tops I posted. Note there is no number stamped but there is a "scribed" OK on the compressor label.
I don't understand anything anymore.

Hi Tom, i don't think you have gotten close enough to this stamping to be sure. I think the zero is the bottom of an 8 stamp and the K maybe sumpthin else. The digit appears too small for a digit stamped in the 1968+ era.

Please see my photo for my thoughts on this

I'm inclined to agree that it's an 8 instead of an "o", and I can see where the staff of the "k" , or whatever it is, has removed some of the paint of the "p" in the word depositato. However, because of the roughness and irregularity of the characters, I'm still of the opinion that they are scribed instead of stamped.

A further examination will have to wait for me to get back to the storage facility and take some better photos, perhaps with some side-lighting to enhance the contrast in the "scribed or stamped" letters.

I'll come back and post the final answer eventually.

By the way, the close-up photos make me realize why the judges of FC2008 concours took off 1 1/2 points for the engine compartment. I apparently couldnt see the "trees" because of the beauty of the "forest". From two or three feet away, my engine compartment is beautiful, but up close, these scratches and paint abrasions become like a pimple on the end of one's nose. They are all that one sees.

Here is more data to consider in horn details. This came from the extensive 246 restoration by OMGJON.
Notice-
1) position of 2 character stamping, sort of randomly too close to edge.
2) additional data text 597-598 617-634 , which i would expect as the MC/1 progressed from 1968 thru to 1973+
3) 3M seems reasonable for a 1973 246 Dino.
4) 710 still apparent
Has anybody had opportunity to get close ups of other compressor tops? It is also nice to record what trumpets accompany the compressor as well.

Fabbrica Italiana Accumulatori Motocarri Montecchio SpA , est 1942
FIAMM
History - FIAMM Group, a family owned enterprise, was created in 1942, serving the Italian government with the production of Electric Utility Vehicles. FIAMM Group is headquartered in Montecchio Maggiore, Italy, about 40 Km south west of Venice, and about 240 Km east of Milano.
more at http://www.miuraworkshop.com/FiammRoadmasterHorn.html

I am trying to put the Fiamm graphic information together in a sensible manner and i have a start. I am not real happy with my format, so it will stay under construction for a while. The goal is to have a good understanding of FIAMM air horns from 1950-1990.
i would like compressor top photos with clear stampings from everyone. Tom Yang Chat is a great website for this sharing.
Tom, can you provide more detail photos or info on the two compressors at this thread start?
thank you all for help on this

Tom Kizer, i would like a better photo of this compressor top without a shadow please and clarification on the stamping.

Here are a couple of FIAMM serie "2000" compressor tags 1971 and 1973 to compare for your info.
thank you
please more photos from other FIAMM owners
