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

I just bought this NOS Colnago Dream art decor.

Does anyone know when it was build? I can't find to seem any logic in Colnago's serial numbers or a decent database..

The serial numbers are: 1D997 and D285

Cheers and thanks!

Airplane tubing? Nice! I'd say anywhere between 1999 and 2011, The one (Rabobank) I used to ride was a 2000 edition and was built exactly the same. My dad rides it now so I don't have it at hand to check the numbers. Will have a peek when I'm at my parents' place.

btw There's a 'Colnago Official' Facebook group nowadays, maybe you can shoot some pics their way
