CONSTRUCTION: The JB has a one-piece nose and body. The base is welded to the body. The JC has a pressed steel nose and drawn steel body. Here the nose and base are welded to the body. The J was the early model of the JB and they are identical in construction. The J/2 is very similar to the JC, the quality of the steel being the real difference. It was produced only in limited quatities. The sheet steel tail cone is riveted to a ring which is secured to the bomb body by eight screws. The small holes on the fins are used to attach screamers.
