Speaking of World War II, a couple of hours ago I took advantage of the Monday Midnight Madness sale at http://pendemonium.com to order one of these new old stock flex nib, piston filler, 1940s German pens they got a hold of, and only after I had placed the order did I put '1940s' and 'German' together.
Maybe they were imported by Prescott Bush. :) I hope I ordered soon enough (probably) and like the pen. They are no-brand pens; probably a Woolworth's somewhere misplaced them.
Update: Sam Fiorella at Pendemonium informs me that my pen will be mailed tomorrow. This pen is so new, it's been new for 60 years already. :)
