Good grief guys! How how can one tell the difference between a B-71 and an SB 2 M-100 from that picture!
According to M. Maslov, in his Tuolev SB monograph (a fantastic book), both captured SB and B-71s operated together in LW service
One way may be the location of the swastika. If it is on the rudder it is a B-71, if it is on the fin it is an SB. Good a way as any.
