I have two delightfully flexible Waterman nibs, both purchased as artist nibs but they are quite different. One is long tined, soft and flexible, in a 52 pen body; the other, short tined, springy flexible, in a 42 safety body. Neither is marked "Artist Nib", though I believe I saw a post here in which the author indicated his nib was marked "Artist Nib". [i][i]My question is, does anyone know whether or not Waterman marked their artist nibs in any way? I have seen a Waterman advertisement showing the music nib and artist nib, but, as I recall, the artist nib had no markings, was short-tined and looks like the nib in my 42 Safety. The music nib was obvious due to it having three tines and two slits.

Not marked in any way. You mean LONG tines (not short). See this old thread Also check this ad that I had posted there. The Artist's nib is the one at the very bottom - right.

Thanks for your reply to my query. In addition to posting my question here, I asked vendors at a pen show how they identified the Artist Nib. The consensus was that it is a nib with good variation between hairline and broad. In that regard, it sounds like the Waterman's Pink could be considered an Artist Nib. I have little experience with the Pink nib but it seems to be very flexible, going from hairline to broad but it is also very springy. One of my nibs, see my query above, is soft and the other springy. What the nib does seems to be more important than how it works.

The nibs marketed by Waterman as the "Artist Point" were unlike the Pink nibs in their extreme fineness of point. Think flexible needlepoint.
