Might maybe be of interest... US Bomber Projects #16 is an extra-sized volume covering the evolution of the B-52.
Designs covered include:
Boeing Model 444 A: A late war turboprop heavy bomber
Boeing Model 461: An early postwar turboprop heavy bomber
Boeing Model 462: A large six-turboprop ancestor of the B-52
Boeing Model 462-5: A six-turboprop B-52 ancestor
Boeing Model 464-17: 1946 four-turboprop strategic bomber, a step toward the B-52
Boeing Model 464-18: a reduced-size version of the 464-17 turboprop strategic bomber
Boeing Model 464-25: a modification of the 464-17 turboprop bomber with slightly swept wings, among other changes
Boeing Model 464-27: a slightly-swept turboprop B-52 progenitor
Boeing Model 464-33-0: A turboprop B-52 predecessor
Boeing Model 464-34-3: A turboprop B-52 predecessor
Boeing Model 464-40: The first all-jet-powered design in the quest for the B-52
Boeing Model 464-40: The first all-jet-powered design in the quest for the B-52
Boeing Model 464-046: A six-engined B-52 predecessor
Boeing Model 464-49: The penultimate major design in the development of the B-52
Fairchild M-121:A highly unconventional canard-biplane
Convair B-60: A swept-wing turboprop-powered derivative of the B-36
Douglas Model 1211-J: An elegant turboprop alternative to the B-52
With additional diagrams of the B-47, XB-52 and B-52B
