The writing instruments date from the time before reunification (before 1989), recognisable by the marking 'W.-Germany'. They are a Meisterstück 144 Solitaire Silver grain guilloché (fountain pen or 147), a Meisterstück 161 Le Grand ballpoint and the matching Traveller case. The cases are: red = Florence, black with cartridge holder = Traveller, black small = Sienna. On gold-plated parts two variants are distinguished — Vermeil (gilded silver, hallmark '925') or gold-plated brass (without hallmark); if the 925 hallmark is missing and only 'Germany' stands on the pencil, it is brass vermeil.
