Beer and kvass mugs (1917 – 1991 years), not souvenir

Description

To be completely accurate, then this particular mug does not have a designation of volume and a verification mark. And the last two photos 5 and 6 are taken from the Internet, where a similar mug has already been verified and there is a designation of volume. Here we can assume that these mugs (both in the volume of 0.5 and in the volume of 0.25 liters) were produced before the war. At that time, the requirements of Soviet GOSTs did not apply to them. In 1946, immediately after the war, mugs began to verify and apply the manufacturer's designation and volume. Most importantly, we know that these mugs were produced in the USSR. The designation of the SKF plant is the first attempts to come up with a logo, where "Kommunar" was placed between the words glass factories. This is common, the most striking example is Artyomov mugs. Where, even over time, the АСЗ was transformed into a САЗ. So the time of release of this mug is from the 30s to 1947. In photo 4 we see her with her older sister. Full match in glass color. Same decision in terms of form.
