Waterman glass cartridge

[Epictete92]

Hello friends,

 

I bought yesterday this nice Waterman for 20$ with a glass cartridge.

I have not been able to find wich model is it, have any idea?

Thanks

Salut encore un fois,

 

The glass cartridge was patented in 1935 and was invented by a M.Perraud, I haven't found a model yet but I'll see what I can come up with, no promises but I'll keep looking, a bientot, John

Is the cartridge a good fit? (That is, is it definitely meant for this pen?)
