There's been a few pairs on here recently.
They will 'most likely' be able to squeeze the dropouts onto a 120mm axle.
I used a 120 on my 130 frame for over a year until recently putting the gears back on it.
Never a prob.
There should also be enough room on a 120 axle to add a couple of washers either side to space it out a little.
Metallic lilac you say!? I best get some sparkly varnish for the Witcomb! ;-)
