Gribakin Benjamin V. (?)

Help to deal with the signature of the artist. I assumed that this VV Gribakin (1907-1974 ). Picture owned by the artist SA Tatarnikova (1907-1987) and is depicted on it myself Tatarnikov in 1944. My assumptions are based on these facts: both artists studied at the Art Academy in the early 1930s , and then the two fought on the Leningrad front. Well, of course , the signature - W. Gr. There may have been familiar with. Maybe someone familiar with the work of Gribakin and can confirm the signature of the figure. Thanks in advance.
