It says it right on the description from WaitsThank you gentlemen!
Got some info on Reddit from /u/kwonza :
A wild guess - it says Военторг ЛенВО.
Военторг is a kind of shop in Russia and USSR where they sell merchendise for the army like uniforms, belt buckels and stuff.
ЛенВО I guess is Ленинградский Военный Округ - army is divided by military districs this one is around the city of St. Peterburg - former Leningrad.
Alex, is your find an East-German model?
Thanks again.
