Hmm, I guess "early" is a relative term but I vote "not early" on this auction. That crank is Dura Ace AX, which came out after a couple earlier generations of Dura Ace.
It's worth noting that those pedal adapters are not original - maybe not even made by Shimano? The adapters came out later to retrofit the cranks to regular pedals, for people who hated or broke (or both) the original AX pedals that came with the crank.
Since this group doesn't include pedals, I take issue with the seller calling it a "complette vintage shimano dura ace group" - the group is not complete without pedals (and brake lever gum hoods). And being a mixture of different generations of Dura Ace prevents it from being a complete group in my opinion, though I'll grant that's a strict definition of group.
In wine making, where the word vintage comes from, when you blend two or more years in one bottle, it isn't vintage anymore, it's non-vintage - though the result can be very good.
And these parts can be very good and a good value - I'm just picking nits about the terminology.
