I imagine the frame with stem and handlebar will bring 100 - 150 GBP on ebay (you should peruse
www.hilarystone.com for a better idea of what you can ask for a frame of this vintage/condition). The rest of the parts, if included, wouldn't change that very much since the buyer would have to pay a lot more shipping.
OMG! Do NOT click that link if you want to pay the mortgage next month.
