I have a question about Campy chainrings, maybe someone can answer here. I have been sorting through my old 144BCD 1970s and early 80s chainrings and I found some that say 'PATENT CAMPAGNOLO' and others that say 'BREV. CAMPAGNOLO', which of course I expect, but I found some that look identical except that they only have a '<C>' and tooth number stamped into one side. In other words, no Brev or Patent stamped on them. They do have the nice finish on them like Campy Record rings. Of course they are Campy because they have the '<C>' stamp, but where do they fit into the Campy timeline and are they Record? They are not Super Record, because they have all the standard chainring webbing. They also are internal rings 43 and 42 teeth. Any ideas? I can send pics if you need them. I also bought some on ebay that were in the Campagnolo 'Record' white sleeves, but when I pulled them out there was nothing but the <C> and 43 stamped on them, no PATENT or BREV.
Thanks,

Dee,
The inner Record rings of the "Patent" era were marked with the <C> logo. As far as I know, they were all like that, and none of the inners (41t, 42t) were actually marked "Patent." The outers were marked "Patent" and they came in a couple of styles over the years. Of the late 60's and later 144 bcd type Record outers, the older ones have no chain pin, and the typeface is smaller and more upright. The newer type had the pin, and the letters were bigger and rounder. I'm not sure if the pin and lettering changed at the same time, so there may be no-pin-with-new-letters, or pinned-with-old-letters versions.
When they started marking them as "Brev." the inners and outers got similar markings. That is, the inners were not marked <C>, they were marked "Brev."
Super Records are another matter, and the earliest inners had "Patent" written out. As far as I can tell, all the Super Record outers had the pin. The later type were marked "Brev." inner and outer. I still can't tell exactly when teh "Patent" to "Brev" change took place. Around 1982, I think.
