Hello,
I have attached an image with a MB 149 18K bi-tone nib another image with the feed (split-ebonite). The nib has a dot sign in the lower right near the 750 mark. See the attached image.
Could someone identify the nib and tell me if the sign/dot on the nib is normal and tell me what is the purpose of that sign?
Thank you for your time!
Best regards,
Florian
