A detailed model of a paddle steamer on a rectangular base: a two-tier superstructure with rows of windows, a funnel, a paddle wheel with its housing, gangways, railings, boats and flags at the masts. Among the factory's presentation pieces the public was especially struck by the mechanical model of the steamer Derzhava, ranked alongside the silver model of the Pedagogical Museum. This photograph is the only known image of such a work.
