Basically, the distance between races can be broken down into two categories: thin walled (more distance between races) and thick walled (less distance between races). Older French cups tend to be thin walled. New cups (80s on) tend to be thick walled. The old Stronglight cups were thin walled.

There is handly info on spindle tapers in older editions of Sutherland's Handbook for Bicycle Mechanics.
