Just saw this pen on eBay today. First example I've ever seen of an all-black Japanese fountain pen (including nib). Judging from the pictures, the nib looks to be a M and reminds me too much of the Preppy, otherwise I'd be tempted to buy it myself. http://www.ebay.com/itm/Platinum-PTL-5000-All-Black-/110952999690?pt=LH_DefaultDomain_0&hash=item19d5506b0a
