Rouge et Noir No. 122
The section end of this particular pen model is rather interesting. Most catalogues for similar models show the section threads right at its tip like safeties from later years. But, this particular pen has a flared section end and the threads that engage with the cap are actually inside the barrel, as can be seen in this picture.
This pen is from the personal collection of Marcwithac - a generous contributor on FPN and vintage pen collector with exceptional taste!
