For Sale: Poyner 531c frame & forks built by bob jackson.57cm

Indeed a lovely looking frame, that ticks most of my boxes.

I have the same questions as dooks, above:

is it build for 27"s or 700c?
and do you know what the rear spacing is?

• but I don't have a nice Witcomb to fall back on, so I'm keeping my fingers crossed that the answers are the ones I'd like to hear. Also hoping pick-up in London is possible.
