Here's a set of scans for fans of 1940s Sheaffer plunger-fillers. Here are three interesting transparency variations in Triumph plunger-fillers. None have internal capsules. 1. A reverse trim black Tuckie c. 1942 with a striped transparent section http://i11.photobucket.com/albums/a152/gmberg/IMG_3353.jpg 2. A green striped Valiant II with a visualated section and a 1/2" view window in the barrel http://i11.photobucket.com/albums/a152/gmberg/IMG_3338.jpg 3. A green striped Valiant II with a visualated section and a full size barrel window http://i11.photobucket.com/albums/a152/gmberg/IMG_3625.jpg Cheers, Gerry
