Yes, 27.2mmno idea of value but that's some lovely stuff . . .
Is the post 27.2mm?
My wife likes red, it’s hers.Check the post thoroughly for cracks!. If the lower half isn't a mess/faded badly, not cut, and it's crack free it's probably worth £80-£100 to the right person.
Saddle - red is an unusual colour, maybe £40?
