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

Description

In the photo number 6 and number 7 shows this same mug, but it produced in 1938. Marking is already not Bukharin plant but ГХЗ. Reconstruct the chronology: 1936 - marking "БУХ", 1937 - or "БУХ", or no marking. From 1938 – “ГХЗ”. Thank you to the distinguished carbonatser for providing photos and descriptions.
