Horn Coating, Painted or Plated Options

[DennisV]

Can anyone tell me what the original coating was for the horns? Most of the ones I have seen are painted...with overspray. (IMG:style_emoticons/default/dry.gif)

Thanks to a pointer in another thread, I have managed to get the ones from our 914-6 working again. Despite several searches, I've yet to find a resource that indicates the proper coating after stripping the cover and the diaphragm.

• 914-635-103-11: Horn - HELLA - 335 HZ
• 914-635-104-11: Horn - HELLA - 400 HZ

Ours prior to stripping didn't offer much evidence to guide me.

not galvanised.

originally the horn on the 914 was black painted.
mine is still original unmolested - the paint on the rear surface is quite intact.
the front surface pointed towards the bumper grille is flakey but still 1/2 there.
i do not believe what is underneath is galvanised metal. its possible but if it is its very thin galvanising. certainly not hot dipped. i'm inclined to believe its a high copper content tin or something like that as a metal.

newer replacement horns manufactured decades later - different story.
not made quite the same as the original 60s / 70s era horns.

OP's photo above shows the black paint clearly.
underneath where its been painted white over the top and is flaking off.

my old squareback i had back in the 80s was the same.
black painted. that was an original factory horn on that car.
