My grandfather left me an old Inoxcrom fountain pen that was given to him as a gift. I have been using it as a dip pen to write with, but am hoping to find a converter so I can use it on the go. I am not interested in cartridges.
I can't seem to find the model of this pen online, and it doesn't seem to fit the standard cartridge/converter size. The reason I say this is because I bought a fountain pen from an old man who hand makes them, and I suspect he sizes them to international cartridge/converter sizes.
Here are some photos of the pen:
