Niche pens used to sell some Noodler's inks. There was also another shop that sold them, but I cannot remember the name right now. I do find #41 a bit dull and have mixed it with Pelikan's brown in the past to compensate for that. I liked the colour more than Noodler's #41 on its own - but once a student asked me to sign a document while I was outside, between buildings. It was raining slightly and the Noodler/Pelikan mix was of course not waterproof... I guess I will either stick to #41 to have a waterproof ink or I will use Pelikan's brown which is more cheerful (maybe even a bit too cheerful).
