The “Leningrad” radio receivers were put into production in 1946 at the Nikolay Grigoryevich Kozitsky Plant. These were radio devices of the 1st class with twelve tubes designed to receive radio broadcasts. They could also play recordings from external media.

This receiver model was quite popular. Even Comrade Stalin had one. In 1948, the device was modernized, and was released in two versions, one of which was improved and had an extended range of shortwave radio reception.

Pavel Petrovich Bazhov was presented with this radio receiver — the first model — in 1949, among many other gifts in honor of his 70th birthday and the 30th anniversary of the beginning of his literary activity.

The radio was presented by the delegation of the Sverdlovsk Uralmash plant. Bazhov witnessed the construction and launch of the plant. He recalled how he had “wandered with a basket” in the area where the giant plant was later built. During his lifetime, the writer visited the enterprise several times, met with workers, held literary evenings, and at the end of his life even wrote a tale dedicated to the technical achievements of the plant.

The tale “The Other Heron” was conceived by Bazhov after visiting the Uralmash plant in 1946. The author described his visit as follows:

In the story, the early-orphaned boy Kuzma goes to work at the factory as an apprentice of a skillful metalworker. He quickly masters the craft and becomes an excellent specialist. But the supervisor, the malicious Kogotok (literary, “Claw”), does not want to promote the boy until he makes a heron — the emblem of the plant. Kuzma refuses, because the bosses always nit-pick when someone makes herons: they say “this heron is flawed”, then they fine the makers and extend their work time. The confrontation between Kuzma and Kogotok lasts for years. As a result, the young man gets a promotion using a different path — by repairing a rare device for a local gentleman. After many, many years, Kuzma, an honored master and a gray-haired grandfather, tells this story to his adult grandson Ivan. Ivan brings him to a modern factory and shows a “heron” — a large piece of earthmoving equipment, which now does not trouble the workers, but on the contrary, makes their lives easier.
