If you actually get an ebay bow for $70, then how could it be fake unless it's not a bow?? Whoever Louis (Loose, Louise, Louie, Luke, Lucifer, etc.?) Mozart, Morizart, Morizot you get the picture;- is, is not too important. For $70, that is just a footnote. Beware of authenticity on Ebay. It's almost always fake. Now if it was an actual bowmaker's name that might be different. Like this Lous Morizot:

But that eBay one doesn't look like it's made by the same hand.
