The guy Meucci should be honoring today is Dennis Hatch. I've seen the old lock and key design on a couple magazine covers because of his playing.
I remember St Louie Louie's name on a George case, but I never saw it on a Meucci.
I remember a thread (from a while ago) where the subject of Louie's Meucci came up, and someone (I forget whom) posted a picture of it. Trying t find it is like trying to find a needle in a haystack, maybe we can start another thread to see if they could report the picture.
