There's a repair shop in San German in the south western part of the island of Puerto Rico. The man's name is Gregory and he is about the only person on the island who does any horn work (or atleast the only oneI can find) He works with the University there nearby Ponce. His son can custom make any mouthpiece and I had one of my mouthpieces dipped in gold for $45. Although the language is a problem if you don't speak spanish they are nice guys and their shop is on the roof of their house. I trust them with my Besson horn so if anyone is on the island, stranded and in need of repair...that's about the only place to go...
