Can you help to identify these frames, bikes or parts?

Found a trashed track frame build up as a roadie in a shed. Was wondering what brand it is since there are no stickers, badges, serial numbers. The details that might help: it's a Reynolds 531 build, has a campagnolo patent headset, think the white paint is original, but the yellow parts used to be blue. Pics:

Hope you guys can help me out!

can't help you out recognising it but if you're selling it I would be interested.
