Christopher, the M.Dv 847 would be very interesting to see, only the title :"Preliminary instruction for caretaking of the diesel engineplants on board ships, submarines and launches of the Navy" written in Gothic letters, what could be a better example of German naval bureaucracy. During the war I was a schoolboy in an occupied country, we normally had English as our 2ND.language to be taught from 4.grade on, howewer the germans changed that and German language became mandatory, including the learning of Gothic letters. It took a while before you could read it . A very interresting detail, the swastika is removed from the eagles wreath.
