Fred put me onto these – the H Plus Son TB14 rim. Apparently Fred knows the guy (to one extent or another) who makes these, Tsuzing. I’m told his dad owns an aluminum extruding plant in China and so… voila. (Check out the video – it’s pretty great.)
“TB14 was inspired by the classic aesthetics of rims from the era when steel frames ruled competitive cycling and benefits from contemporary improvements in rim manufacture and profile design. We have always admired the look of the classic box section rim. From sourcing double eyelets to crafting new molds for the valve badge and its hardware, we dedicated neurotic attention and careful detail to every aspect of this rim.”
At 490 grams, not the lightest rim on the market – in fact the same weight as the Sun CR-18 rim. But it has a few things going for it that other rims do not. 
For example, apparently they’re a little wider (23mm) which, when paired with 23mm tires gives you handling remarkably similar to tubular wheels.
These rims are also anodized after they’ve been welded and processed. This means that not only do they benefit from the hardening after all the real work has been done to them, this also means the braking surface is the same color as the rim. An aesthetic point I admit, but pretty cool nonetheless.
There are a couple places you can order them from. I bought mine here…

…who charged me neither tax or shipping. I could be wrong but I think they’re a newer shop – wander over and take a look at their site.
At any rate, these rims will get laced to a pair of Campy Centaur hubs for the Paramount and I’m stoked. Speaking of, it’s back from the Powder Coater; I’m just waiting on a few small things (like these) before I build it back up.
Onward.
