Thanks both.
M10 + SPNK looks promising: I dug out my SPNK Fixxer and the bearing seat is pretty much perfect and found a rear axle out of a R501.

That won't fit your fork ends, which is why I suggested the axle out of an M525 or M756 front hub, as they already have the required step down to 9mm at the ends.
Thanks, didn't realise that, assumed I'd have to get them turned down.
