According to collectors, the 94 fountain pen and the matching 95 second instrument in solid gold were made between 1960 and 1970, so a pen carrying either number can be dated to the 1960s. Two-digit model numbers are typical of the Montblanc range of those years.
The 750 hallmark denotes 18 carat: the body is solid gold, not merely gold-plated or covered in rolled gold. Versions such as these were the top of the range at the time and were produced in far smaller numbers than the precious resin models, which is what makes them sought-after collector's pieces today.
No reliable information exists on the original packaging, the accompanying papers or the recommended retail prices of the day; these questions remain unsettled. What counts in placing a particular example, then, is above all its state of preservation, the soundness of nib and mechanism, and legible hallmarks.
