I want to replace the sac on a lever fill Waterman. It is marked 52 on the end of the barrel. When I look up sac replacements I find sacs for two pens: 52 ½ V (#15) and 52 V (#17). Nothing for just plain 52.
I have a sentimental attachment to this pen. It belonged to my father. I'm not a pen fixer, just a user. It is in pristine condition and I'm nervous about doing this myself.
Advice would be appreciated.
