There was a pipe on Ebay for the longest time that was a basket pipe with the wrong stem on it (tenon was about 1/4" longer than the mortise) in the bing crosby shape. It was stamped Crosby and was probably older than I was but the seller posted it as a pipe made by me. I emailed him and corrected him and he took my name off the auction.
Too many eBay sellers use "I am not an expert." or "I know nothing about these." as a "Winky of Absolution", which rights all wrongs. If you really don't know about an item, say so and mean it. Most of these give some impression that they are more that they are.
