A picture of the original Bosch horn still attached to the underside of the car. Check out that floor pan, not bad for a 50+ year old car.

Disassembling the horn
The interior of the horn looked perfect, however it didn't work. Upon closer inspection I noticed the contacts (not visible in photo) had a lot of corrosion built up. After cleaning the contacts and reassembling the horn, it worked perfect.
A few of the horn pieces after bead blasting. In addition to these two pieces, all the original hardware was bead blasted and nickel plated.
