The only way to stop this kind of thing is to stop the sale and ownership of ANYTHING that has been 'restored' a bit. And that kind of draconial measure could never happen. There is probably more stuff in circulation that has been put in a more acceptable condition than the totally genuine stuff. Some of us are realists over this subject -and are prepared to accept such items. As long as we pass them on, stating what they are - with an honest description, we are doing nothing wrong. The onus is on the new owner to be just as honest when they sell it.
