The series of 'Mighty Eighth' books by Roger Freeman, particularly 'The Mighty Eighth' and 'The Mighty Eighth in Colour', not only lists and describes all 8th AF units and their operations, but includes photos and colour profiles of a number of the assembly ships. The '..in Colour' book, as the title suggests, is filled with colour shots, including some of assembly ships, many of the pics being of excellent quality, as if taken yesterday. Well worth looking at.
