Seafire I hope you don't think I'm intruding on your post if I attach this which has a pic of my old bunker which can enlarge.

Memories! I was finally deported to British boarding school and I miss the old Bunker. Least you could have a smoke and a drink and a pork chop without being flogged half to death by your form master. And those helpful little fellers from the Hitlerjugend knocking out the odd Soviet tank when they became noisy.

Joking aside, I actually lived in 11 Selchowstrasse in Berlin for 2 years when i was 6-8. That belonged to Herr Doktor Morrell Hitler's Surgeon
