I have a pen with a generic (not rebranded) #6 JoWo screw-in nib unit (steel nib). I have 2 questions.
1. Will an Edison #6 screw-in nib unit "probably" fit the threads in my pen barrel? IOW, is the threading on the #6 JoWo nib units standardized?
2. In terms of replacement of the nib ONLY in the screw-in unit, will the #6 JoWo nibs rebranded and marketed by Goulet, Anderson, etc., fit into the assembly of my JoWo unit?
Note: I did searches for answers to these questions, but I was not successful. If this info is located online already, please let me know.
Thanks
