Greetings All, I've been searching a while and can't find a list of pens that take JoWo #5 nibs. If you could say which pens you have successfully put these nibs in without any adjustments or violence to the pen or nib, I believe many on here would be very appreciative. Plenty has been said about #6 nibs, but not so much on #5s. Note: I'm specifically referring to #5 nibs made by JoWo alone and just the nibs themselves, not feeds or housings. I also mean nib-pen combinations that have actually been tried successfully, not theoretical possibilities based on measurements (I've found that nib thickness and other variants have been the undoing of many alleged claims to swappability). Thanks for your help!
