some 30 years ago I discovered a bunch of discarded strange ink cartridges which did not fit a modern pen. I was lucky at that time to find a local shop that still had a pen in which those cartridges fitted. That was my introduction to a Diplomat pen and I have been using it almost on a daily basis since.
As you can see in the images below it concerns 6/99 cartridges for a Diplomat +2. However searching on those keywords does not give me any relevant information. As far as I know this type of pen is dated end of the '60's / begin 70's? It looks the same model as the one that was offered in the following link: http://www.fountainp...pen-sets-fp-bp/
So my question is if someone has more information regarding this (type of) pen from Diplomat.
As you can see in the images an 'F' is present on the bottomside of the pen. The Diplomat logo is present on both ends of the pen. I found this to be a very durable pen which writes nice. It sure would be nice to get hold of another Diplomat pen in which these cartridges fit.
Thanks in advance for your feedback Hopefully someone can shed some light on this pen and cartridge system. Any information is welcome.
