my 'sense' of the individuals in the group is all guesswork so if anyone here can confirm or deny or fill-in the identities, i'd be much obliged.
for my part i'd suggest the following names:
seated, L to R: UNKNOWN - perhaps Izraileva/Zubkovskaya?; Olga Moiseyeva, Boris Shavrov, Nikolai Zubkovsky(?); B.Y. Bregvadze
standing, L to R: Aleksandr Gribov(?); UNKNOWN; V.Chabukiani.
