My thanks to the many people who have offered their support, through clicking on 'ask a question', many of whom I've never spoken to before. I don't know whether the listing will run until the end, but your comments send out a clear message to eBay.
1079edmund removed his plaque with fake anchors from eBay. A jug with a ship with orange/brown over-painted sails sold for £87, which is far less than it would have made if he'd just listed it without over-painting. There were no bids on this item in the last 5 days of the auction. A child's mug, currently at £51 comes up on Tuesday night. I'll keep you posted.
***The child's mug received no further bids. 1079edmund decided to remove the Mariner's Arms jug with a mixture of original and fake enamels.***
***Two buyers have left follow-up comments on eBay to say their items were over-painted. Another buyer of an over-painted item contacted me today. 1079edmund has no items listed at present.***
