Making of various large guns at German armaments factory - probably Krupps.
Unused / unissued material - dates and locations unclear or unknown.
Fantastic, almost surrealist footage of German workers making grand weapons (long range guns, light antiaircraft guns, heavy antiaircraft guns and guns for submarines) in German armaments factory - most probably Krupps. German voiceover, very dramatic, dark, Wagnerian music. Mobility of a giant gun is demonstrated - great low angle shot up the gun.
Sound stops at (01:21:46). More footage of the men assembling guns.
Note: probably captured German footage - UFA material.
