Hi Peter,
It helps a lot indeed. If the first location is right it could indicared a co-location with Lw.Bef. Mitte, please see:
http://www.gyges.dk/Gefechtsstand%20...te%20reich.htm
In the spring of 1944 Lw.Bef Mitte had been renamed Lft.Reich and they moved their Gef.Std. It would be logical for 30 JD to do the same, and locate in a seperate facility.
And as you can see here.
