Michael,
I was actually trying to indicate that what I was saying applied only to rings of the 144 bcd era. That said, I'm interested to read this: "The 42T (144) ring on my 1978 Benotto is marked 'Patent'," because it shows that I was mistaken whan I said, "As far as I know, they were all like that, and none of the [144 bcd, patent-era] inners (41t, 42t) were actually marked "Patent." I think need to go look again at my pile of rings. Maybe what I was really thinking is that there are no 144 inners marked "patent" in the older (smaller and more upright) typeface. Of course, the 151 stuff is older than all this, and they were marked "Patent." So, if this revised timeline is correct, it narrows down the date of the <C> inners to after the introduction of 144 bcd, and before the change to the larger and rounder lettering (which may coincide with the addition of the addition of the chain pin).

Tom and Dee,
I'm not sure Tom's assessment that Record (151 bcd) inner rings were only marked with the symbol and nothing else. I've checked the 44T (151) ring on my 1962 Masi, and it is marked "Patent Campagnolo" My spare NOS 44T ring (aka retirement fund) is also marked Patent. The 42T (144) ring on my 1978 Benotto is marked "Patent," while the spare is marked "Brev."
