I was just reading through the March 2006 "Adventure" magazine (by National Geographic) and there in the back, in the ads on page 99, was something similar.
The "Trekker" by Fisher Space Pen is shown. Looks very close to the Inka Pen. A trip to the Fisher web page didn't turn up any Trekker pens. Perhaps this is a new product...
