Well Friends,
With some of the caution about not soaking a Waterman Le Man 100 or Waterman Le Man 200 (let's be specific here) being mentioned, all I can say is that I have soaked (1) Le Man 200, (2) Le Man 100 and (2) Opera nib-feed-section assemblies for varying lengths of time in room temperature water with absolutely no ill affects. -- None. Zero, that is. Meaning that only good came out of the soaking.
The one Le Man 100 nib-feed-assembly I soaked for more than 2-months. The others were for lesser amounts of time but not less than 5-days on the down side. The only thing that was destroyed was the caked, dried ink inside the catacomb of the ink feed.
I experienced no problems with the finish on the section of these particular pens - even the gold plating remained in tack and unharmed. And it was based on my specific multi-pen experience that I made my initial suggestion.
That being said, there are pens for which soaking overnight is not recommended. Unfortunately, I have destroyed my fair share of them. But with the excellent results I've achieved from my non-destructive cleaning approach for these specific pens, I stand by my recommendation.
I have never use ammonia to clean a pen. That is just my preference. I have, as was so kindly suggested to me, applied just a bit of dish washing soap to the ink-in side of a feed. (With wonderful results.) However, I am exceptionally careful to make certain that I know exactly what the results of a cleaning or a repair procedure is going to be before I make any suggestions to a person.
Water can be a friend or an enemy. In the case of a nib-ink feed-section assembly for a black lacquered Waterman Le Man 100, Waterman Le Man 200, or Waterman Opera, soak it in room temperature water as long as is needed.
Peace,

Phroneo,
Based on your experiences, I did the plan water soak/rinse/blow/refill/repeat on my Man 200 for just a couple days
til the feed appears to flow water nicely. Even lightly blowing some water through after each soak refill it was
amazing how many times a couple hours later would still show some ink leaching out. There must be all kinds of
nooks and crannies up in that nib. Just waiting on my converter to arrive now (pen came minus one), I've alnost
"jumped the gun" and just flushed out a Waterman cartridge and refiled with the ink I plan to use but figured
I'd work on my dimenished quality of patience and wait on the converter.
