Mr. Nicol. No.
Mr. Eisenberg. Mr. Chairman, may I have this admitted as 622, please?
Mr. Dulles. 622 and 623.
(The items referred to were marked Commission Exhibits Nos. 622 and 623, and received in evidence.)
Mr. Dulles. Would you just briefly describe these?
Mr. Nicol. This represents another position of the cartridge case, the head of the case—you are looking at the rim, and this is the portion of the head stamp representing millimeter. This was a 6.5 millimeter. You see just a portion of the "5." And what I will be talking about is the marks down against the rim in all of these exhibits.
Now, this is the same cartridge as represented by these other two photographs, with a slight rotation.
Now, we have only one which we might have to pass around. But if the photograph 621 is placed in a position corresponding to the arrows, a match of the fine striations, the pairs of broad lines as well as the fine lines, can be seen.
The reason that this could not be taken under the comparison microscope is that because of course we cannot divide the cartridge case, so that this had to be done photographically rather than being done on a comparison basis.
Now, this illustrates the fact that the same operation occurred twice on this particular cartridge case.
