A Dutch museum devoted to beachcombing, of all things, recently discovered an odd object in their archive that has left them scratching their heads. According to a local media report, officials at the delightfully-named Strandvondstenmuseum, which roughly translates to 'Beachfinds Museum,' found the puzzling piece in a storage area among more easily-identifiable pieces of fishing equipment as part of what is believed to have been a collection that had been donated to the facility.
Upon spotting the oddity, administrators at the museum, who have presumably seen all manner of maritime paraphernalia, were positively baffled by what the mysterious piece may have been. It's composition would appear to be metal as the group has dubbed it the 'aluminum drop with wings.' Another clue is that a visitor to the museum who happens to be an aviation expert observed that the object is hydrodynamic rather than aerodymanic, meaning that it was designed for use in water.
