hi friends a few days ago I got a personal photo album of a luftwaffe. unfortunately I did not find his name in the album, only places where he probably served - Marburg / Lahn, Biedenkopf / Lahn. please ask me if you advise me where to look, adding a few pictures from the album maybe someone will know. thank you in advance for your comments

Well, WBK is probably referring to Wehrersatzbezirks Kommmando Marburg. I’m guessing the first picture is a proud Father and his sons.

BlackCat-yes you are right, thanks for the advice!
