The one I'm working on now(pics soon, I promise. Just gotta get it looking less than hideous) is stamped "31 Trinacria" (I'm presuming this is a model #) on one side, and "FSCO. Caminiti, Messina" on the other. Aside from determining that it's a Sicilian blade, I can't find a scrap of information about the maker. Google has yielded nothing but a few links to data from some swim meet.
Come on, you brainiacs. Throw me a bone here.:)
