On the last car I took the original horns apart, cleaned painted and reassembled. They then sounded terrible, so I sent them to Julian Hardy for tuning, and he did a great job.
Learning from last time, I will not take these apart. Simply will remove the front grill, sand all parts, primer and paint. Tuning will all stay the same- because they already sound perfect!
Some notes: I have already removed the original data plates on the front of the horns and carefully restored them. I'm really happy with how they came out. There are replacement data plates out there, but they are not correct for 356 C cars. Below are some photos of the data plates right after I removed them. Covered in layers of paint and crud. Not wanting to sand off the actual data on the plates, I had to carefully chip off the paint and then polish. They came out very well.
One of the photos shows the "before shot" of the back side of one of the horns- yuck! Note the date code stamp of 501. Both horns have this same stamp, which represents January of 1965- definitely the original horns! Now it's time to make them beautiful again.
Bottom shot shows one horn face in final/restored condition. Really pleased with the look. This one is 6/15, which is the low tone horn and goes on the passenger side. 6/16 is the high tone and is for the drivers side.
