Becareful What You Wish For
Would you rather the seller knew exactly what he had and like so many others, up the price into the several hundreds?
Poorly researched and or written adverts for vintage anything are a treasure for those who know what they are doing. Were the thing listed on eBay as it was originally, someone would have nabbed the deal of the year if not century.
If as a seller you do not know your stock, or what you've got, that is not my problem. One is quite happy to relieve an ignorant vendor of his merchandise at well below market, never letting on.
