I will be selling a Montblanc 146 Solitaire in Sterling Silver on behalf of a friend. The pen is boxed with warranty, in excellent condition but unusually does not any hallmarks.
The warranty shows a date of December 1995 but I would suggest that manufacture was probably around 1991/92. Of note are the stripeless ink view window and the 8 digit serial number on the clip in the earlier font style.
Were the earlier silver solitaires manufactured without hallmarks or, did somehow this pen escape the 925 stamp?
