You can see "Battle Numbers" on the tail fin of these B-26. That indicates that they are flying with either the 17th, 319th or 320th bomb group and my guess is that they are from the 17th or 319th.
Battle numbersIn October of 1943, 48-inch high battle numbers were ordered to be painted on both sides of the plane's rudder. These battle numbers replaced the "last three digits" of the serial number that had previously been utilized for aircraft identification. As in pre-war Air Corps practice, aircraft of the first Squadron were asssigned numbers between 1 and 24, the second Squadron, 25 to 49, the third 50 to 74, and the fourth squadron 75 to 99. The 320th painted its battle numbers below the serial number in military block-style (angled corners) and were usually wider in stroke than other MTO units, namely the 319th and 17th. Initially, battle numbers were painted in white, but by the end of 1943, after the 320th moved to Sardinia, the group color, yellow, was used in order to better distinguish the ships in combined formations. When natuaral metal planes started arriving, as with the tail banding, the battle numbers were outlined in black.Serial numbers were changed to black as well.
