HELP IDENTIFYING SOVIET 35mm FILM

Here´s all the information I have of one 1,500ft long (approx) reel of film that I have recently purchased.

• It is a #3 reel from a feature.
• Black and white.
• Dialogues are in Russian.
• (Subtitled in Spanish)
• Triacetate base.
• Mono sound.
• Stock seems to be Gevaert from Belgium, copied from Kodak stock (date code: 2 triangles, most likely 1941).
• Label on the can reads Sovexportfilm, with no markings on it except for a "3" that I assume belongs to the reel # and a "Исп" which I assume is short for Испанский (Spanish), which leads me to believe that it was subtitled in the USSR.

"Vivíamos en la misma calle en Leningrado"
(We used to live on the same street in Leningrad)

"Pero en la guerra me persuadí..."
(But during the war, I was persuaded that...)

"A su salud, Mayor."
(To your health, Major)

Any and all help will be greatly apreciated.
