On a Solitaire Doué shown in the discussion, the star on the cap appears unusually angular and "jagged", differently than on the original with clearly rounder points. A comparison with the cap of a guaranteed genuine Solitaire 144 Stainless Steel confirms this difference. Added to this are a hardly credible nib design that rather recalls models of the 1950s, an unsharply taken photo and a seller with only few ratings. Before a purchase, additional detail photos should be requested; in case of doubt, the auction is to be advised against.
