Hello all! I know this has been answered on a few other threads, but I could use some more help. So I bought a Sheaffer vac-fil with a triumph nib and was wondering the best way to go about making it write. The pen is in semi working order, but the piston hasn't been greased in about 50, so it's stiff (don't want to force it) From what I have read, it sounds like the nib unit needs to be removed, so how is the best way to do this (without a ton of fancy equipment)? Also what is all this about "packing material" what is it? does it need to be replaced? Thanks, Alexander
