Hi Jura, thanks for getting in contact with me.
the data above contains information about a commander of a german WWII uboat. Adalbert Schnee wasn't officially set in command, he was a representative in command of the submarine ("Vertretung im Kommando" in DE). I will take a deeper look later this week.
