I have just got a beautiful English aerometric Parker 51 from 1965, but when I flushed out the dry old ink the press-four-times filler slowly started letting out water at the opening where one pushes.
I assume that the pli sack has gone loose and either has to be replaced or re-glued with shellac - which leaves me with some questions:
1) How do I get the filler out? (It certainly is not easy to get it out and I don't want to use to much force.) Is it correct that it is not screwed in? Does it help putting it in warm water?
2) Any advice on what size of pli sack I should get will be appreciated, as will any advice on what brand of shellac to use and any details with regard to the procedure in general.
I have looked all over FPN but I have found very little on the subject, so if you are experienced in these matters please give me as much advice as possible.
