Contracted to be built for France in 1940 and later contracted to be diverted to Great Britain as AM927, this Liberator was the 25th built out of a total of 18,482 B-24s. The total number built is documented as 19,267 with the inclusion of all variants. In 1967, the B-24 was loaned to the Commemorative Air Force who eventually took full ownership of the aircraft in May 1968. In 1972, AM927 was painted in the colors of the 98th BG, of the Ploesti Raid, and given the name Diamond Lil. During 2006-2007 the aircraft was reconfigured back to her B-24A/RLB-30 roots and was given the Ol' 927 nose art.

In April 2012, the CAF’s long-time Liberator legacy and nose art Diamond Lil was returned. On May 26, 2012, Diamond Lil experienced a complete hydraulic failure and suffered a subsequent nose gear collapse, in Charlotte, North Carolina. Temporary repairs were made and the aircraft was flown back to Addison, Texas. Because of the need to fabricate many replacement parts, restoration was not complete until July of 2013. Since mid-2013, Diamond Lil has been touring the U.S. providing new and older generations the opportunity to experience this rare aircraft through aircraft tours and ride flights.
