I just acquired a Waterman Sleeve Filler with a wet noodle nib and did some research on its production - all I can find online is that it was apparently patented in 1909 and that it was produced from 1910-1915 before Waterman lever fillers went into production. The problem here is that my pen is labelled thus: "Pat'd 1884 May 23, 1899 Waterman's (Ideal) Fountain- Pen N.Y. U.S.A. & Aug 4, 1903" This inscription is on the sleeve itself. Any advice? Photos below - I hope they show up, it's my first time adding photos to a post. http://i76.photobucket.com/albums/j30/egglorru/Screen%20Shot%202016-04-02%20at%205.09.28%20PM_zps1ewkfsgs.pnghttp://i76.photobucket.com/albums/j30/egglorru/Screen%20Shot%202016-04-02%20at%205.10.00%20PM_zpsq161rxln.png
