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

It could be lots of things, but it does look a lot like a couple of Cougars I had. Cougar was Terry Dolan, and at that time he built a large number of the frames for UK pros - that were then badged up.

Paganini was, I think, a name that Plum in Belgium put on frames that were built for them in Italy. More recently a UK sprayer has used the name, but there's no connection with the originals. The top-line Paganinis had an engraved head tube, and so are easy to spot.

Thanks for the info, I'll try and find some pics. Cheers
