Mr. Cunningham. 602, 603, and 605 are your copper-coated lead bullets of Winchester-Western manufacture.
Mr. Eisenberg. And 604?
Mr. Cunningham. And 604 is a Remington-Peters lead bullet.
Mr. Eisenberg. Now, were you able to determine whether those bullets have been fired in this weapon?
Mr. Cunningham. No; I was not.
Mr. Eisenberg. Can you explain why?
Mr. Cunningham. Yes, sir.
First of all, Commission Exhibit No. 602 was too mutilated. There were not sufficient microscopic marks remaining on the surface of this bullet, due to the mutilation, to determine whether or not it had been fired from this weapon.
However, Commission Exhibits 603, 604, and 605 do bear microscopic marks for comparison purposes, but it was not possible from an examination and comparison of these bullets to determine whether or not they had been fired—these bullets themselves—had been fired from one weapon, or whether or not they had been fired from Oswald's revolver.
Further, it was not possible, using .38 Special ammunition, to determine whether or not consecutive test bullets obtained from this revolver had been fired in this weapon.
