Chain size for Vittoria Margherita, Cambio Corsa etc.

Can someone please tell me what chain width was typically used originally on bikes equipped with Vittoria Margherita, Campagnolo Cambio Corsa and Paris Roubaix?

Thanks!

Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

The early systems used 1/2 x 1/8" chain for up to 3 rear sprockets. Later on when they went to modern systems with 4 or 5 speeds they switched to the narrower 3/32" wide chains.

It's easy enough to know which you need if you measure the sprocket at the roots of the teeth. Sprocket width is slightly under the nominal chain width.

Typically, prewar derailleurs, VM and CC, used a 1/8 chain on a 3 speed. Postwar derailleurs, CC and PR, used a 3/32 chain on a 4 or 5 speed.

There are always exceptions to the rule.
