Steve,
sadly he passed this summer, last year he told me where the flak was but due to his health we were not able to take him out to the area as I wanted.
I miss his stories, he was a character.
If I find anything of interest in your area, I will post it up here.
It is all doom and gloom at the moment as another good friends wife has just died unexpectedly, he is struggling with it and I have vowed to make more time for him and drag him out to some of his local battle sites (Winsen Aller). We were chatting and he said he has a possible aircraft site in Meissendorf but his pal in the know, has also just recently died.
We are quite busy sorting the shop for Christmas and I have a lot of shifts due to people on the sick.
If you have any other interests in my general geographic area feel free to ask and I will try my best.
Best
Rich
