No help there from me, Tom, sorry!
Last friday I did some research at the Red Cross. I checked the files of the missing Dutch NSKK-men. I ran into small tragedies: a woman looking for her husband, a dad looking for his son, a nephew looking for an uncle, etc. All of these men were gone: 'maybe in the Russian zone', 'has probaly died near Sarajevo', 'was last seen in a Russian camp and died there'. SOme of the letters were written as early as 1945, others as late as 1987. Not a great read after all. I can use a lot of the information in the end, still it's a tragedy to read these letters of familymembers and the Red Cross.
Always in need for info about: Dutchmen in the NSKK, HJ and TeNo.
