Danke Herr Echolot: you live up to billing! Awaiting my Rosetta Stone to improve my poor Deutsche...at least up to my Spanish. When rising too rapidly to attack inside the convoy ala 'Silent Otto', a mysterious voice whispers "Oberteil Nicht Zusslagen"- slows me down and saves hull integrity! Might be my great grandma Sara Koenig from Bavaria; we still recite her nursery rhymes as passed down 3 generations. My neighbor from Hamburg laughs at my Bavarian accent!.
