Okay. I give up. I know that I'll live to regret this, but I'll take a stab at a Cinelli dateline, though I am 100% certain that I am not 100% correct. Or probably even 50% correct. But, it's a start. Feel free to add, delete, or edit. Go ahead, unsheath your knives and tear me apart This should be fun......
