This is a slightly more elaborate iteration of a pipe horn noisemaker, but that can't disguise the fact that this is a fantasy item. These are being actively manufactured in Germany and sold by such peddlers as robodicki. Unless you don't mind tossing money down the sewer, avoid buying these.
I'll begin populating this page with photos of reproductions, fakes and fantasy items as I see them listed on eBay, Etsy and other such sites. Hopefully, collectors will refer to this page to minimize the occasions reproductions, fakes and fantasy items are unknowingly purchased. If you see something on this page that was sold to you purporting to be a vintage item, immediately send it back for a full refund.
