This aluminum flask was made at the Leningrad plant "Красный Выборжец ", 
a famous manufacturer of ammunition for the Red Army.
A flask, a mug, a spoon and a mess kit were included in the Red Army soldier's field equipment.
At the bottom of the flask you can see the stamp "Красный Выборжец 1939"/ “Red Vyborgets 1939”.
The reverse side has a concavity, as if it was bent, but why is not clear.
Canvas cover, probably later.
The flask does no leak.
Volume 0.7 liter.
I combine shipping costs for all lots.
All items will  be sent by airmail with tracking number.

Due to the criminal aggression of Russia against Ukraine, the delivery time for parcels is increasing.
But the post of Ukraine works, the parcels go to Poland, and then they are delivered by airmail.
