Hi there. I'm new so please bear with me. I have a pelikan pen. No idea what style. I can't find info on it.. I have not used it in 30+ years. I was ctrying to remove the stuck nib. Didnt know i should soak it first. I removed the gold nib, the rubber/plastic bit under it... But the housing is still in the pen!!! Help!! I've been soaking it firvthree days now to release all dried ink. I am pretty sure i used water soluble ink as i stillv have the bottle. Suggestions?
