Mr. Frazier. It would be—that is right; at the dividing line, the circles on 544 are drawn close to the dividing line, which shows only a very small portion of the firing pin of that cartridge case.
Beginning with number 1, it has a gently sloping ridge running from upper left toward lower right in each instance, with a break in the ridge contour at the middle in the form of an extension upwards toward the top of the photograph.
In number 2 there is a circle drawn around the end of a very long line in the left-hand side of the photograph. The circle is drawn to show a Y-shaped break in this line located on both cartridge cases.
Number 3 is a photograph of an irregular-shaped raised portion on the firing-pin impression, which is very difficult to describe in words.
Number 4 is a groove extending from upper right to lower left which has a break in its lower side to allow a horizontal groove to come in towards the main groove. The lower portion of that groove coming in from the lower side is in the form of a crescent-shaped ridge, which starts horizontally from the left and then falls off towards the lower right-hand side of the photograph.
The circle, number 5, is again a Y-shaped or wishbone-shaped ridge, with a horizontal bar on the right, and then extending ridges upward toward the left and downward to the left.
Mr. Eisenberg. Again, are these firing-pin marks what you would call strongly characteristic?
Mr. Frazier. Yes; I would say so.
Mr. Eisenberg. Does the firing pin give any evidence of having been altered subsequent to the original manufacture?
Mr. Frazier. No, sir; only in an accidental sort of way, that is, very fine scratches which may have been caused by firing or dirt on a cartridge or something which may have scratched the firing pin.
