You remind me that there were (and are) a bunch of interesting stores in the little business district of Lichterfelde-West. I bought maps – new and old – at the antiquariat there. On a reunion trip I found a reprint of a history of Lichterfelde that answered a lot of questions. For example: it turns out that the Imperial cadet school that became Andrews Barracks was part of a real estate scheme. That info made me feel right at home.
