You are right on point (so to speak!) about collector terminology. I'm hardly a fundamentalist myself about strictly following original manufacturer's model names, especially when a given model went through multiple name changes during its run.
"Waverley", however, is problematic on a few counts. The main one is that a real Waverley nib has a shape completely different from any fountain pen nib (a handful of rather uncommon Macniven and Cameron fountain pens excepted). Here's a picture: http://www.londonanc...ountain-pen.htm
So instead of being useful, "Waverley" applied to turn-up nibs is, above all, confusing.
As already noted, the use of "Waverley" to describe nibs made by companies other than Macniven and Cameron is also anachronistic. No other penmaker used the term while Macniven and Cameron was still around, and from what I can see it didn't shut down until the mid-1960s. Nor can I find any evidence that anyone, either penmaker or collector, described turned-up nibs as "Waverley" nibs until just a few years ago. There is no history to the usage within the pen collecting community. It's a brand-new coinage, and most older collectors will just look at you blankly if you use it. It caught me totally off-guard when I first ran across it in 2009.
"Turned-up" points, by contrast, are mentioned constantly in old ads and catalogs. You can see a bunch of them listed in this 1882 Perry list: http://books.google....AAQAAJ&pg=PA152
There's a bunch more here in this Hunt's ad from 1909: http://books.google....AAAAYAAJ&pg=PA3
If you look at the Waterman 1908 catalog (downloadable from the PCA reference library), on p. 55 you will see a picture of 8 nibs, the fifth from the left described as "TURNED UP" and shown from the side for good measure. The text below includes the following: "Turned-up Pens or ball points of different degrees of fineness." (boldface in original)
The 1912 Conklin catalog (also available through the PCA) has on p. 19 a mention of special nibs, including "pens with turned-up points".
These are just a few examples. If you dig through old catalogs and ads (as I spend far too much time doing), you see "turn-up" and "turned-up" nibs mentioned over and over and over. There's no question that this was standard terminology -- so really no need to adopt a new name for a feature already perfectly well named.
