These are threaded nibs & not friction fit nibs. The outcome is more an initiative of ASApens. The threaded nib are an integrated unit of nib and feed.
Like other fountain pen manufacturers Gama selected German made nibs and feeds to evolve their traditional eyedropper pens. Did this revolution or evolution discard the ebonite feeds? I like the ebonite feed in my traditional Gama Supreme eyedropper since it can be easily cleaned and custom fitted to a particular nib by heat setting the ebonite feed. Have I changed to OEM nib? No, but I am considering it. The nib Gama installed in my Supreme writes well, but it is a German #6 nib which is about 35 mm long. A longer nib would probably be more ergonomic for me, since the pen feels more comfortable for me with its nib inverted.
As to longer nibs you can always ask ASApens. You can even ask for a gold nib #9 size !!
And i understand you can also get the same jowo gold nib in friction fit set up from ASApens. The nibs are same nibs whether you buy from meisternibs or goulet or asapens
