From the dimensions, several Meisterstück models come into consideration: a 149 would be clearly larger, a LeGrand 146 likewise, so only the Classique 144, the Hommage à Mozart or the Hommage à Chopin remain. In favour of the 144 Classique speak the length of about 135 mm, a single-coloured gold nib type and the single gold ring directly in front of the nib. A missing model number on the cap is not an exclusion criterion, as not all Classique models bear such marking. For safe identification, collectors recommend comparison with the detailed model overviews on fountainpen.de as well as close examination of detail photographs.
