I don't know how common it was to use two chainrings with these "finger" type of gear changer mechanisms. I recall seeing photos of bikes equipped with Campagnolo Cambio Corsa gear changers with double chainrings. Considering that the rear quick release has to be loosened in order to change gears, it must have been quite an operation to shift in front!
