Probably a waste of time but please report this. Look at his feedback, he's making a small fortune from these "Siege pieces" or is he ? .I think we've reported this scumbag before on numerous occasions. He must be the luckiest guy on earth with all these "siege pieces" he's finding.
Could be shill bidders also. It's the same buyers winning his stuff and the feedbacks really phoney and arse kissy possibly a fake feedback scam to sucker people into believing these fraud pieces are legit.
