On the nib :
314
R. Esterbrook relief( Im assuming "relief", as the 'r' is under the barrel)
Altogether, capped around 6"
I love how it has a cap, and plan to use it as a test pen, when Im trying to choose an ink. It's just a very pretty little thing, and I'd love to know more about it....anyone got any information?
Also any advice on care, cleaning, and if/where such replacement nibs are available....
I hope it's ok to post in more than one place - wasnt sure where this should go. Mods. please give me a gentle ticking off if I shouldn't have done it
