So I phoned the number (mobile) and had a chat with a bloke. After a bit of schpeel he said "Make me an offer"... chancing it I said "Grease or oil bearing?", he instantly came back with "Oil" (indicating he's looked into it a bit) so I said "Tell me what you want for it, I can only say yes or no..." and he came back with £500. "Errr.. no thanks. Call me back if you can't sell it, I'll offer you between £150-£250 depending on condition and testing".
Did I do good?
