I've got a full suss frame in the garage, 13" if I remember rightly.
It has been primed by its previous owner so would need finishing off, althought it's quite flaky so might be easier just to rub it back to the original paint.
It's nowt special, Apollo XC26 I think, weighs a fair bit, but you're welcome to it for nothing if you want it.
I'm in Warrington.
