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

Don't know a huge amount about steel pinarello's but I think the Treviso was also made from Aelle.... May be worth considering.
Probably worth searching Flickr too, see if you can find a paint-job match, most are blue-white-blue fades rather than the white-blue-white!

Thanks Rik, I've been trawling Flickr but you are right, all the other colour schemes are reversed...
Treviso or Venetto it is!
