Komanos, GR or Lvov, SU ?

[Foreigner]

Sorry for OT, but technically, it should be either Lvov, Soviet Union (SU), or Lviv, Ukraine (UA). In that time frame the city can be viewed as either a part of the USSR (СССР), or UkrSSR (УкрССР), but not part of Russia proper (RSFSR, РСФСР).

In the Soviet Union, Russian was considered "the language of inter-nation communication", so Russian spelling was "the more official one", and would be more properly used with the "SU" option.
