Steven's mention of his Cooper prompted me to download some pictures of my
example. Last year I was lucky enough to have Ron build me a bike from
NOS 531 with a 1" toptube. The idea was a mix of old and new, so it has
over the bb cable routing and this old style tubing diameters (plus the
lugs, etc), but it was spaced 130mm in the rear and is set up as an
entirely modern bike. It's one of the best riding bikes I've ever owned
and part of the reason that I have sold off nearly all other "modern"
non-lugged bikes...at last. Anyway, this link should get you there if you
are interested and there are albums of the Herse, Mariposa, Singer,
Rivendell, etc., under my nom du yahoo, which is dvicakrababa.
