It looks very similar to this one from Restoration Hardware:

That exact table in the photo is, I believe, this one from Noir:

It is 84.5" long, though. Is it the X-base that you especially like? Or, the zinc top? If you can't find something that is the exact right size for your needs, you can always have one custom made, but that will be more costly...
Have you done searches for "zinc top dining table?" I did a quick one and found this:

I am still working on it. I just contacted SDS designs re: making a custom table. I will check out your leads. Thanks. I love the Zinc top and the wood x base. Need 72" b/c I have a built in window seat I'd like to pair it with.

Just checked Clapton gray home. Not a fan on the base.

I see.... if you have the physical space for the 84" length - you could always add an extra chair to the end of the table that extends beyond the window seat? Otherwise, custom will be the best route. Good luck!

Bernhardt has a similar table, the Quentin.

I ended up getting the Hudson table from www.zinhome.com. Very happy with our purchase it's 76" with extension leaves on each end to for 106" total length.

I saw one similar to this online at Z Gallery.
