Mr. Cunningham. This is approximately 123½ times.
Mr. Eisenberg. Congressman Ford, would you care for a discussion of this?
Representative Ford. No. The one previously gave the basis.
Mr. Cunningham. Actually, this seems to be a slightly larger area. You have again the same "railroad tracks," all up and down, going across the two cartridge cases.
Representative Ford. To the layman that seems even more——
Mr. Cunningham. Demonstrative, yes. I don't know if you saw the photographs of the cartridge cases in the rifle, the assassination rifle. Those marks are just as distinctive as the more demonstrative marks in this particular breech face. But to a trained examiner, they stand out. They are harder to see than those on these particular photographs. And even in these photographs, the photograph you were asking me, they were not quite as vivid as they are on this photograph.
But there, again, it goes back to what I told you—each cartridge case will strike the breech face in a slightly different way, and you don't get complete similarity.
Mr. Eisenberg. To illustrate your point, Mr. Cunningham, I hand you Commission Exhibit 565, which is a photograph, which was explained yesterday, of the cartridge case fired in the rifle, and a test cartridge.
Mr. Cunningham. Yes, this demonstrates it very well.
This is the very rough surface on the bolt of the assassination rifle.
