Montblanc Meisterstück L139 Long Window Wartime Fountain Pen
The 139s are hard to date because they were made for a quite a long time, but this is a war time pen so it will be early to mid 40s.
This is an amazing example of a Long Window. Mint Long Windows are VERY Hard to find. And this one is almost that. Its a stunning example.
The imprints are perfect.
The window is very clear clear, and the feed is a flat feed. The pen has the correct 139 250 Palladium Nib. The nib is a B nib with has some great flex.
The pen is a fantastic example of one of the most collectable Vintage Montblancs.
It fills via telescopic Piston Filler.
The pen is fully restored by one of the most well known and respected restorers Osman Sümer.
