JoWo compatibility.

[gbryal]

Lots of pens use JoWo nibs. Some use JoWo nib units. A few that I can think of are Edison, TWSBI, Franklin-Christoph, Bexley, the Rangas cut for JoWo units from Peyton Street Pens. I think Rosetta pens also use the screw in units.

I bought some nibs from MeisterNibs.com the other day, and noticed that while they fit in both of my Edisons, they didn't fit in any of the other JoWo pens, though I think all were #6. I suspect the nibs themselves would fit, but the screw in units weren't compatible.

Just wondering, which units are compatible with which pens, and if there is a name or model number for the different varieties.

I believe Bexley steel nibs are JoWo but fitted to Bock feeds inside Bock units. Franklin Christoph nib units should be threaded the same as Edison though, for their respective #6- and #5-nibbed pens.
