I just disassembled a newly-arrived Sheaffer imperial I (blue plastic), and found that the sac was torn. More perplexing, though, was the internal structure of the Imperial I — once I obtained a replacement sac, where was I to put it? Does it go onto the little thingummybob through which the breather tube is threaded?
And assuming that I could find a place to shellac the sac, I thought I should replace the O-ring just in case; but I can't find a way to release the blind cap from the tube.
I'd be most thankful for any guidance my betters could offer this flummoxed amateur.
