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

Yes, they're the vertical campag ends on my Colin Cape TT bike.
I was using that image to illustrate why a frame might be built with the drop-outs cranked inward like the ones on @pavemann 's mystery frame.

I see where the confusion may arise.

From the side view the horizontal dropout does look like it's been bashed into shape and linished so it may not have been made like that (this may explain why it has no markings...)
