this is another source, probably the same manufacturer. i purchased one (vertical, with perforations) five years ago. still love it, and used these numbers:

I bought my mailbox from them too, Maude -- same style, but black and without the perforations. It looks fantastic, and the quality is very good. Way cheaper than RH, too.

I bought the large one in black from Mailboxes.com too!

the RH one does seems to have some extra edging material on the top and does not have exposed rivets... so it looks a bit more "beefy". granted, many folks are not into the "trimmed" look and would prefer the simple bent-metal edge of the one you link to above... in any case, i'm glad to see RH again offering something a bit more modern. i was a bit bummed when they switched to their victorian "soap, sheets and towels" model. previously, i was always able to find something vintage-industro-cool there.

I have this Ecco mailbox that I just love.

Their entire line is strangely compatible with Arts and Crafts, Modern, and Industrial. When I move, it comes with me!

And, for good measure, this place does fabulous house numbers.

Their site might be a bit hokey and infuriating to navigate, but their craftsmanship and customer service are outstanding. I got the Craftsman>Grove set (numbers 5613) in 1/8ths Aluminum for my small 100 year old brick bungalow. And along with that mailbox, they really made the front of the house so special.

$89?!

Or free if my sheetmetal tradesman partner makes me one from off cuts. :P
