Which model Dura-Ace wheelset?

Can anybody give me a steer on these Dura-Ace wheels? Which model are they?
I've tried looking at the rims and hubs for a model number but can only see the 'Dura-Ace' logo. They are clinchers - 16 spoke radial type pattern on the front and 20 spoke pattern on the rear (radial type pattern on the non-drive side and cross-spoke on the drive side).
They ride very well but I'm debating whether or not to keep these Dura-Ace wheels or to put on some Fulcrum 1s.
Thanks for the anticipated help - I've included some photos to see if they are of any help.

I have very expensive deep section rims and very rarely use them I use my dura ace clinchers for racing.

The Dura-Ace roll nicely, the Fulcrums look the part.
Decisions,decisions!

That will be the obvious plan in the next week or so.
My OP was to try to determine the Dura-Ace model, as I had bought the bike secondhand (a Scott CR1 Team) with the DA wheels on and wanted to establish a rough price on the DA set, should I decide to sell them and keep the Fulcrums.
