No. 12 Safety
This pen is from the personal collection of Joudenali. Watch out for reviews of truly rare pens from his treasure chest!
The No. 12 Safety was manufactured between 1924-29. We know this particular pen was made in 1923 thanks to the imprint on the barrel which was not at all a standard imprint and probably signifies that the pen was only meant for internal Montblanc use - it could have been saved for archiving, or as a sample for sellers, or it could have been a prototype before launching the standard production.
Another rather special characteristic of this pen is its nib - a BBBO triple broad oblique right probably best for left-hand writers. I have never seen this nib advertised in vintage catalogues of the time and it was definitely not a standard offering.
Finally, the clip is rather unique too. I have personally never seen it in any book or catalogue or picture online even. It is beautiful!
This is the largest size MB pen ever made - just look at it next to the 149 (leftmost) and 139 (second from left) and No. 45 (rightmost) in the picture! I have had the opportunity to hold a No. 12 and it is exceptionally large. This pen is not easy to come by at all, and the price is anything when you do! The No. 12 is also found in black (see review here).
