91mm front hubs?

I've just starting to build up my first fixed gear bike, starting with an old (1960-ish) Viking frame. Nice Nervex lugs, but needs some paint love, etc.

Only thing is that the front forks have a 91mm spacing, and narrow drop-outs that won't accept a QR hub. And according to teh great Sheldon at http://www.sheldonbrown.com/frame-spacing.html, 91mm hubs are "Low-end front hubs."

Oh.

So, before I throw the towel in and replace them with something a bit more modern, but rather less related to the frame, does anyone know where I might procure a front hub that would fit?

bend it?

New forks. Easy and cheap.

Some japanese front hubs are 90mm spacing, apparently it's an old NJS standard as well

Easier on the back, where at least the triangles will stop you bending it wonkily. Front forks would need a jig and some expertise, I think, so you don't end up with alignment problems. Which are virtually guaranteed with my manual dexterity...

Yep, if I can't find a hub, that's exactly what I'll do.

Yeah, apparently Shimano still did them until fairly recently (two/three years ago) but I've had no luck at all actually locating any.

4.5mm either side then, just pull the fork legs apart and put the wheel in?
