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

saarf
i'd say colnago crystal

Did some more research on this one (https://www.dropbox.com/sh/gqere87uabo0dqb/AAD32zaFSiUtDbvQwRFEcd9ga?dl=0) and I think it's a '94 Elegant.
Reasons why I think this: seatstay-lug C-stamp, completely chromed rear triangle, the "complexer" lug-cuttingg, the fact it's pretty light, the serial number starting with a "4" and this '94 catalogue and the fact the seatstay has a smaller diameter near the seatstay-lug. What do you think?
