To nie jest tarcza do K-43 tylko do Toczmecha. Jeżeli dobrze pamiętam, to po obaleniu cara powstał Trust o nazwie Toczmaech i oni składali zegarki z części (np. szwajcarskich) pozostałych z przedrwwolucyjnych manufaktur zegarkowych(albo jakoś tak
)
Na netgrafik zanlazłem coś takiego:
Watch industry in the Czar Russia consisted just of several small workshops and enterprises. They usually assembled watches using watch parts made abroad. After the 1917 Bolshevik revolution, the entire watch industry became a part of the “Trust of Precision Mechanics”. These were mainly production facilities, work shops, and warehouses of watch parts and half-finished products which belonged to famous manufacturers such as P. Bure, G. Mozer, Reinin, Dmitriev, and others before the revolution.
