Mr. Cunningham. I did.
Mr. Eisenberg. Did you make your identification on the basis of the photographs or on the basis of your examination under the microscope?
Mr. Cunningham. My conclusions were arrived at strictly on the basis of my examinations. These photographs in no way entered into the identification and are strictly for demonstrative purposes.
Mr. Eisenberg. Could you show us these photographs, Mr. Cunningham?
Mr. Cunningham. Yes, sir.
Mr. Eisenberg. Let's take them one at a time, and let's introduce them as exhibits, one at a time. I have here—you have given me five photographs. Did you take each of these photographs?
Mr. Cunningham. As a matter of fact; I did. I personally took these.
Mr. Eisenberg. And these are photographs of what?
Mr. Cunningham. They are photographs of the individual characteristic marks on the base and in the firing-pin impression on test cartridge cases obtained from Oswald's revolver, and also the marks on the base and in the firing-pin impression on the cartridge cases, Commission Exhibit No. 594.
Mr. Eisenberg. Mr. Chairman, I would like these admitted, if you would, as 596, 597, 598, 599, and 600.
