Mr. Eisenberg. Are firing-pin marks usually as characteristic of a given cartridge case as the primer marks?
Mr. Frazier. Yes, sir; I would say they are as characteristic. However, they may not always be as evident, they may not be seen as readily. However, they are just as characteristic.
Mr. McCloy. Just to repeat again, what is this side of this picture? What does this represent?
Mr. Frazier. That represents the rifle cartridge.
Mr. McCloy. The rifle cartridge itself?
Mr. Frazier. Yes, sir.
Mr. McCloy. And this on the right?
Mr. Frazier. This is one of the three cartridge cases recovered from the building, Exhibit 544.
Mr. Eisenberg. Mr. Frazier, you fired two test cartridges in the rifle, is that correct?
Mr. Frazier. We fired several test cartridge cases. These two are the ones that were used in the comparisons.
