Further to the search for Spreckles' career detials I came across this publication in Danish(?) which mentions our man Spreckels a few times.
It appears to be the wartime memoirs of Uffz.Siegfried "Napp" Rudschinat, who appears to be a close contemporay of Spreckels.
Anyone with the necessary translation skills throw some light on his early career?
It looks an interesting account from Rudschinat himself as well.
