I found this little gem of a vintage pen that needs some restoration work. The pen is probably made of celluloid, it is a self-filler and needs a new sac to hold the ink, but the most amazing of it is the nib. It is a flex nib, very soft and rather springy, that goes from fine to broad easily and without effort. It is so soft that out of the five pens I found in the shop only this one had an intact nib,
See these two write / drawing samples:
The nib is hard to read. I believe it says "Pluma STYB", which would be a Spanish brand. However, I have yet to confirm this. If you know better, let me know. I am really looking forward to fixing it and using it for some drawings.
