Subject: [CR]Hub gears with narrow spacing

Anyone know anything about the SRAM/Sachs Elan 12-speed Hub? I don't know when it was made but I understand it no longer is. I see mention of it on: http://www.sheldonbrown.com/seven_speed.html.

I'm looking for a hub gear with the narrowest possible spacing, and don't even care how many gears I end up with, so long as they're narrowly spaced, meaning no more than about 15% apart, preferrably half that.

I ask here because I don't think such a thing is still made, at least not in spacing under 135mm. Please, all you hub gear afficiandos, educate me a little as to what may be out there in the used or new marketplaces that might do what I want. The bike for this is my Brompton which currently has a recent vintage S/A 3-speed. I think the ratios are move like 25-30% there.

Many thanks in advance.
