Aircraft Markings and Color Schemes
B-24 Liberators (January 1944 – July 1945)
Original Paint Scheme: Dark Olive Drab and Neutral Gray factory finish.
- Circle K Group Marking: Applied in early February 1944.

- Tail Number: Repositioned in yellow below the Circle K on the tail.
- Call-Letter: A 24-inch high yellow call-letter was placed below the tail number. All four squadrons used letters from A in alphabetical order, excluding C, which was not used by the 458th Bomb Group.
- Initially, there was no visual means of distinguishing an aircraft’s squadron until mid-March 1944, when SD110 squadron codes were painted on in blue-grey, either 48 inches or 54 inches high, aft of the waist gun positions on both sides of the fuselage.
