three rounds of Western 6.5-millimeter Mannlicher-Carcano ammunition in rapid succession. A paraffin test was then performed on both of his hands and his right cheek. Both of his hands and his cheek tested negative. 95

The paraffin casts of Oswald's hands and right cheek were also examined by neutron-activation analyses at the Oak Ridge National Laboratory. Barium and antimony were found to be present on both surfaces of all the casts and also in residues from the rifle cartridge cases and the revolver cartridge cases. 96 Since barium and antimony were present in both the rifle and the revolver cartridge cases, their presence on the casts were not evidence that Oswald had fired the rifle. Moreover, the presence on the inside surface of the cheek cast of a lesser amount of barium, and only a slightly greater amount of antimony, than was found on the outside surface of the cast rendered it impossible to attach significance to the presence of these elements on the inside surface. Since the outside surface had not been in contact with Oswald's cheek, the barium and antimony found there had come from a source other than Oswald. Furthermore, while there was more barium and antimony present on the casts than would normally be found on the hands of a person who had not fired a weapon or handled a fired weapon, it is also true that barium and antimony may be present in many common items; for example, barium may be present in grease, ceramics, glass, paint, printing ink, paper, rubber, plastics, leather, cloth, pyrotechnics, oilcloth and linoleum, storage batteries, matches and cosmetics; antimony is present in matches, type metal, lead alloys, paints and lacquers, pigments for oil and water colors, flameproof textiles, storage batteries, pyrotechnics, rubber, pharmaceutical preparations and calico; and both barium and antimony are present in printed paper and cloth, paint, storage batteries, rubber, matches, pyrotechnics, and possibly other items. However, the barium and antimony present in these items are usually not present in a form which would lead to their adhering to the skin of a person who had handled such items. 97

The Walker Bullet

On April 10, 1963, a bullet was recovered from General Walker's home, following an attempt on his life. 98 The bullet, which was severely mutilated, weighed 148.25 grains. 99 This bullet had the rifling characteristics of the C2766 rifle and all its remaining physical characteristics were the same as the Western 6.5 millimeter Mannlicher-Carcano bullet. However, while the bullet could have been fired from the C2766 rifle, it was severely multilated and in Frazier's opinion could not be identified as having been fired or not fired from that rifle. 100 Nicol agreed that a positive identification could not be made, but concluded there was "a fair probability" that the bullet had been fired from the same rifle as the test bullets. 101
