Weinmann concave rim vs cheap modern weight

I'm looking to shave a few grams from an old Fuji I have. The bike currently has old and new 27 inch wheels (36 spoke) - Weinmann concave on the front (laced to what appears to be Campy Nuovo Tipo), and Sun M13II (assuming a generic hub) on the rear.

Weinmann concaves are known to be bombproof, but heavy, anchors. I am pondering upgrading to something more modern and light.

I cannot find any Sun M13II locally, but I can find a front Sun CR18, reasonably priced.

But I see here, the CR18's weigh 620 grams:

And I see here, the Weinmann's weigh 525 grams!

Granted, the Sun's are double walled, but can these weights really be correct? (I've no time to actually weigh the Weinmann rim myself). I guess the Weinmann's are not as "boat anchor-ish" as I'd thought!

Perhaps I can shed some grams elsewhere.
