Subject: [Classicrendezvous] Cinelli stem timeline and questions?

Sorry if this has been hashed out before...

Can someone briefly list (or point me to a timeline showing) when the 1A, 1R, 1E and X/A were introduced and (except for X/A) when each went out of production?

What is the difference between a 1A and a 1E?

Bonus question: When did the various Cinelli logos (or no-logo) appear on these stems and on handlebars?
