A trimmed version of this image is used as Fig. 2-53 (page 59) in Smart, Jeffery K., Medical Aspects of Chemical and Biological Warfare: Chapter 2 - History of Chemical and Biological Warfare: An American Perspective, Textbooks of Military Medicine, Borden Institute, Maxwell-Gunter Air Force Base[1] (published 1997) where it is described as:

The text referencing this image states:

For middle-range tactical support, the Chemical Corps standardized the M79 sarin warhead for the 762-mm Honest John rocket in 1960 (Figure 2-53). The rocket had a range of 16 miles, and the warhead held 356 M134 4.5-in. spherical bomblets, each containing about 1 lb of sarin. A smaller warhead was standardized in 1964 for the 318-mm Little John rocket, which held 52 of the improved M139 4.5-in. spherical bomblets, each holding 1.3 lb of sarin (Figure 2-54).

The Historic American Engineering Record claiming this image is "ca. 1943" is implausible, and probably relates to the fact the photo was found at the Rocky Mountain Arsenal which was established in 1943.
