I'm not exactly sure B-rad. It looks like a youth hostel or something, and maybe the writing is the date the HJ group pictured stayed there. All speculation on my part of course. I'm starting to collect some Norkus related photos when I see them now to display with my insignia grouping.
Thanks Brad, and thanks to Bobby for passing the set on to me. I'm working on a small Norkus display now, insignia, photos and a nice period book. Photos when it's done!
This photo has what you want from the Herbert Norkus Unit - Bann 201 with the Ost Berlin triangle .
