ISO: Campy 50T 135 BCD chainring, classic silver alloy color

I'm building up a bike for my wife, and have a 52/40/30 Racing T triple. She'd be happier with the outer ring being a 50T.

Trade stocks: The 52T Campy ring. Also, a lot of Suntour bits: numerous 6 & 7 speed freewheels, 8 speed cassettes, a 42T ring, and more. Let me know what you're looking for.
