Does anyone know if the square crown fork was used on Super Corsas or Speciale Corsas? If so, when was the sloping crown introduced? I know that the square crown was used on track models and the Model B. Also, does anyone have info on when and on what model chrome tipped forks and chainstay "socks" were used? Finally, Did Cinelli definitely eliminate the bottom bracket drain hole in 1965 or could it have been a bit earlier?
