So I bought a random NOS German button-filler fountain pen with a new sac from a seller on eBay. The nib is certainly flexible, but some of the time it railroads immediately. Occasionally it will write fairly consistently and I can produce multiple flexed lines. Other times it will skip and hard start just in normal use. The tines look like they are little far apart. I tried moving them closer together, but to no avail. The pen is pretty old, but I have no idea if it has an ebonite or plastic feed. When the pen feels like writing it is quite wet.
Are there any solutions I can try at home with minimal chance of destroying the pen? I would rather not take it apart. I hope this is the right forum for this question.
