Here is a Horn ready for assembly. Most Horns placed on my web site have been completely taken apart and thoroughly cleaned in my shop. The Horn and it's parts are dipped into an EPA approved solution to remove any grime, biological, or metallic residue which can build up after years of use. All parts are given a warm soapy bath, scrubbed inside and out, then flushed thoroughly with clean fresh water. When any major dents, broken braces, re-solder needs, or other repair issues come up, the Horn goes to my local Repair Shop.
