1949 Umber Sheaffer Touchdown Statesman - fine/extra-fine

In 1949 Sheaffer did another one of their surprise lane changes. They replaced the entire Triumph line with the Touchdown. While the Triumph line was named for the first pen model - sort of like US Navy ship classes - the Touchdown line is named for the filling system. The Touchdown filler is pneumatic and includes a sac. It's not an intricate or complex filler but it is somewhat difficult to explain the technical details. I find it simplest to liken it to a bicycle pump. That's not entirely accurate, but it's not too far off the mark. Unscrew the knob, extend the Touchdown tube, submerge the nib/feed/section in ink, close the Touchdown tube, wait a few seconds for the sac to fill with ink. Wipe off the section and you are good to go. The operation, apart from the few seconds waiting at the end, is exactly the same as the Vacuum-Fil. The primary failure mode of the Touchdown pens is the end of the barrel. There is an o-ring groove inside to provide a seal with the Touchdown tube. This
