The Meisterstück 144 of the 1980s and 1990s is a cartridge fountain pen into which a piston converter can also be inserted; an earlier 144 from the 1950s was, by contrast, a pure celluloid piston fountain pen. Both the Noblesse series and the 144 have meanwhile been discontinued and are at most still to be found as collector or shopkeeper stock with smaller dealers. Buying from providers in Hong Kong or China is urgently advised against, since there counterfeits are frequently shipped, even when the photos show originals. Added to this are higher shipping costs and customs fees on foreign purchase.
