Just a moment, Philippe! I'm try remember 😉
"java", "Prima", i think.

Very old USSR brand Kazbek, Belomorkanal. very strong tobacco, cigarette without filter. real hard core.

i know one famaly anecdot about Belomorkanal cigarette brand.

Second wife of my great-uncle was a prima dancer in troupe of Omsk Russian Folk Choir, after leading choreographer, was many toured in her life. So, after tour in Argentina, dancers from Argentina arrived to Omsk with a return visit.
Cool, super. During the intermission one of Argentine dancers came to the scene employee & asked him for a cigarette. So, scene employee was very old man, Petrovich. Petrovich didn't know foreign languages, but he exactly understand international gesture of smokers. And of course, Petrovich didn't smoked Pall Mell, Camal or etc. Petrovich smoked Belomorkanal cigarette. And, yes, Petrovich gives to Argentine dancer a cigarette Belomorkanal.
All russian: administrators, translator, another staff - were shocked when they saw it. Oh, what's happen now?
Argentinian took a cigarette (very strong tobacco, cigarette without filter), inhaled a few times, blew smoke rings and said with a dreamy look: "oh,super, very cool, marijuana!!!!"
