Hi All,
Sorry about the incorrect size in the header.

They list it as "This tap fits the current Meister Nib style #5 feed assembly and the Schmidt roller ball conversion feed. Use a "B" drill bit for this tap." implying that there is only one tap.
I've just emailed then regarding the set or no set. I'll post the response.
Cheers
Inky
