I have this little series of photos, purchased on Ebay, showing the visit of a Soviet delegation to Shanghai in 1954 - one of the shots shows the semi-built Sino-Soviet Friendship Hall - and now I wonder whether some of these people are the architects Viktor Andreev and Kaleria Kislova, the engineer Lev Gochman and the sculptors Lev Kerbel and Lev Muravin.
There were other photos in this series, which I didn’t buy.
For comparison, here are the confirmed photos showing the Soviet team on site
