Avant 1918 Please help to identify

[Painter]

Avant- Soviet period. Represented by two seamen from the cruiser Aurora . My opinion is clear that it is written from life portraits of actual participants in the events taking period of the Winter Palace. Individuals are written very carefully photographed with a thicker layer of paint than the rest of the painting . Oil /plywood . Size 53H42 see art direction is clear to me personally . But the picture as often byvet without a signature. Who could be " ranked " authorship? What would a respected publikum ? The subject is interesting one.
