Correct Aldo. This one is actually shown in The Dancing Chain. It's a later prototype of the Campagnolo Paris-Roubaix; the guide's been moved from its normal position on the upper run of the chain to the lower run of the chain so it would shift pedaling forward instead of backward. It was made in the early 1950s (the original was introduced in 1949) after the innovative 1951 Gran Sport derailleur made the Cambio Corsa and Paris-Roubaix derailleurs obsolete. A desperate attempt to make an obsolete derailleur salable (my opinion).
Bikes equipped with this prototype would need a stop at the front of the dropout to keep the wheel from being pulled out of the dropout while pedaling forward to shift gears. Riding the Bianchi shown in the photo would be pretty problematical if not actually unrideable if a gear shift were undertaken.
