This gun is a standard 16 Gauge boxlock dating ~1900-1910 due to the cartridge length being stamped in cm (6.5) rather than in mm.
The bottom plate writing traces it to a successor to an offshoot of the V-C family rather than the main V-C concern.
US value would be on the low side e.g. well below $1000.
No real historical value, I am afraid.
The gun was confiscated by the Germans during WWII and reproved in 1941 in Suhl. Then it was probably "liberated" by the Red Army.
This is very common actually.

P.S> the cast-off amount seems quite large!
