Mr. Eisenberg. Could you discuss the markings on this picture, Mr. Frazier?
Mr. Frazier. Yes, sir. In Commission Exhibit 562, there is again the vertical dividing line which is the top of the prism in the microscope which divides your view. On the left hand side is a portion of the primer and a portion of the head of the test cartridge case from Exhibit 139. On the right side of the photograph is a portion of the surface of the primer and a portion of the firing-pin impression of the cartridge case, Commission Exhibit 544.
To assist in pointing out on the photograph some of the areas where individual microscopic characteristics are present, I have had circles drawn, circling at the top, number 1, an oval-shaped depression in the metal, having an irregularly shaped or wavy ridge across the bottom of the circle. Immediately below that is another ridge which has a flat top, and is more or less of a diamond shape.
Number 3 circle is over a very coarse, wide ridge separated by two fairly deep grooves on each side.
Number 4 circle is over a conical-shaped raised portion on the primer which represents a dent in the metal of the bolt face, and number 5 again is a raised area on the primer which is a portion of a ridge. In this instance this is more or less of a compound ridge which runs horizontally with a small break in it pointing down toward the lower left.
Mr. McCloy. Is that same break apparent in the left hand photograph?
Mr. Frazier. Yes, sir; it is. Looking very closely and right at the hairline, you can see the break in the ridge where it forms more or less of a Y. The actual connecting point is not present, but you can see the portion of the ridge as it heads towards the horizontal ridge. The hairline has separated that portion of it.
Mr. Eisenberg. Would you call these marks strongly characteristic marks, Mr. Frazier?
Mr. Frazier. Oh, yes; very characteristic. They are primarily characteristic because of their irregular shape. If they had been regular in shape, it wouldn't have meant nearly as much as it does to have the irregular rough surfaces and contours of the marks.
Mr. Eisenberg. I think you have identified the next picture I am holding as having been taken by you?
