The Solitaire Meisterstücks of the newer construction were only produced from 1987; the model numbers 1443 (fountain pen) and 1633 (rollerball) in vermeil fine grain fall in this phase. In 1999, the fine-grain models were discontinued, and later, on the Faden models, the vermeil version was replaced by gilded brass. Gilded fine-grain writing instruments without 925 stamp would be untypical for the 1970s and must be examined more closely on photos in order to rule out confusion or later modifications.
