Rare Vintage Gucci Leather Belt in Black w Chain Style Buckle EUC

Beautiful black leather vintage Gucci belt, purchased at the flagship store in Rome sometime in the late 1960’s. Leather appears to be alligator, although I could be wrong as I’m not an expert. (Aka Marmont Caiman). The belt is 1 5/8 inches wide. With the buckle in the first (largest) hole, the belt is 37 1/2 inches around. In the smallest, it is 32 1/2 inches around. Leather is stamped with a “110” which I presume is the size in centimeters of the leather. Leather is in excellent condition- The belt looks barely worn. Chain style buckle it also in excellent condition.
