This chainring came to me mounted on a Racing Triple crankset. Since I'm not young and not skinny, I put the original 50T chainring back on. I can't tell you what gruppo it's from. I'm pretty sure it's designed to be used on a 53/39 double (closeup photos at URL below).
I'll take $20 shipped (USPS Priority) for the chainring.
I have a Campagnolo 53T chainring I would just assume GIVE away! I would love to trade it for a 50T ring. The 53T is almost useless with the smallest four cassette cogs.

Campagnolo 53T Chainring
Used but with lots of life left. No hooked teeth.

I have a campagnolo nuovo record 43T chainring. The ring seems to be the lamination of many (up to 20-25) different layers of aluminum. Like a book that got wet, this chainring is heaving up in some places (looks like it has zits in some places) as some sort of "rotting" process causes the aluminum in the middle of the ring to oxidize. THis is most noticeable by looking at the inside of the ring, where you can see all the thin lines, and some of them are spread by upto 1mm in the worst case.
1. why are these chainrings the result of laminations ??
2. what are in the laminations ?? different types of aluminum ??
3. does campy make any chainrings that aren't laminated ?? because this one sure died an early death because of it.

That's the distinctive effect of salt water corrosion in aluminum. You can see cranks do that occasionally as the oxides (which are larger than metals) split the grain open, allow more salt water, repeat. Odd in a chainring. Was it stored damp??
