It's worth trying to fix, as the OEMs like that are really nice.

Take it apart and clean out the rust. Try not to tear the paper 
gasket.

Find the spot of tar on the back and dig out the tar to see if you 
can turn the adjustment screw. Clean out any dirt from the contacts 
inside.

Put it back together and test it. Turn the screw and find the place 
where the horn is loudest. DO NOT turn the screw while it's sounding. 
Alternate: turn-sound-turn-sound, etc.

I have one here that is perfect except for an open coil. I don't 
understand what could have gone wrong with that beautifully potted 
coil, but I'd love to fix it. The potting is just too tough to dig 
out without damaging the coil.

Let me know how it goes, as my '69 horn has also given up on making 
anything close to a serious sound.
