"Well that is an interesting part, too bad it is kinda beat up. It doesn't look like it is chromed, I would think most of the Confentes out there are show bikes, it certainly would not look appropriate on a nice bike. Now if someone had a early 70's bike that was well ridden, used as a racing bike but not abused, well then that binder bolt would look right at home on a bike like that. I wonder if there is such a bike? ( ;
Back to the question of weather Mario made components, my guess is that he had that made But that is just a guess, am certainly not an expert on what Mario did or didn't do just a big fan of his bikes

The binder looks just like the ones used in Medici's. Except for the lettering which would then read "Rexart Medici". I wrote the seller and he said the binder did come out of a Medici.
