Yep...single flex mounted M2.
Standard issue for B-17F's and possibly late E's and early B-17G's
Believe it or not there was a an experimental B-17 variant, the YB-40, which was designed as an "escort fortress". It was a B-17F with another *powered" turret with twin .50's above the radio room, twin .50's in each waist position, and the familiar chin turret which would become standard issue for the B-17G. The YB-40 carried no bombs, but twice the ammo load. The plan was to intersperse these in the rest of the formation. The YB-40 was an operational failure because with all of the weight, it couldn't keep up with the standard forts after they dropped their bombs.
