My son, unbeknownst to me, had all three of the horns on our 1963 Eldorado completely restored. We had recently added the Eldorado trumpet horn to the two standard horns and the sound was not very good... we had heard good ones so we knew something was not right... but there was not much we could do to get better sound from the 3 horns.
There is a restoration service called The Horn Works who my son contacted and sent our horns off to. I was completely surprised and amazed at the brand new appearance of the horns, but mostly the SOUND of them! They rebuild the horns so you get the original horns restored and all the part numbers are still correct. I am attaching a link to their website and a photo of our finished product installed. We are quite pleased with their service and restoration of our horns.
