Mr. Eisenberg. I hand you Commission Exhibit 595 and ask you whether you are familiar with the cartridge cases contained in that exhibit?
Mr. Nicol. Yes; these are two fired cartridge cases designated K-3 by the FBI and marked with their identification marks—CK, JH, and RF.
Mr. Eisenberg. Now, for the record, these cartridge cases were earlier identified as having been fired by the FBI in Commission Exhibit No. 143, the revolver believed to have been used to kill Officer Tippit.
Also for the record, I obtained these cartridge cases, both Exhibit 595, which are test cases, and Exhibit 594, which are cases from the murder scene, from the FBI, and transmitted them directly to Mr. Nicol for his examination.
Mr. Nicol, did you examine the cartridge cases in Exhibit 594 to determine whether they had been fired from the weapon in which the cartridge cases in Exhibit 595 had been fired?
Mr. Nicol. Yes, sir; I did.
Mr. Eisenberg. And can you give us your conclusions?
Mr. Nicol. It is my opinion, based upon the similarity of class and individual characteristics, that the four cartridge cases in 594 were fired in the same weapon as produced the cartridge cases in 595.
Mr. Eisenberg. Mr. Nicol, did you take photographs of the comparisons?
Mr. Nicol. No, sir; I did not.
