" в 1912-м году вышла модель Turact 8x (бинокль выпускался параллельно с Telact-ом). Он стал намного легче и меньше предшественника, однако хуже по оптическим характеристикам."
Доброго! Судя по инфе отсюда http://home.europa.com/~telscope/zeissbn2.txt Модель Turact 8x24 серийно выпускалась в 1914-1933 гг. Номера 1000000-1550000 относятся к диапазону 1919-1930 гг. Так что можно предположить, что предмет Веймарский, начала 20-х. С уважением,
1920-й год выпуска. Кофр - оригинальный. Верхние призменные крышки - сплав цинка (у немцев напряг с цветными металлами после войны).
