Technology Museum - Moscow

Dear Friends
of interest in Moscow is also the Technology Museum http://www.moscow.info/museums/polytechnical-museum-at-the-ilinsky-gates.aspx
similar, in its conception to the Deutsches Museum in Munich. It presents the Russian and Soviet achievements in the different field of the technology. It has a section devoted to the space technology, but no so so spectacular as the sections of the Memorial Museum of Cosmonautics in the same Moscow. Of interest the full scale model of the first soviet atomic bomb, similar to the second american atomic bomb. A board inform the visitor that the model does not include the atomic explosive.
Any comment from your side is welcomed.
