Below that a pair of lines, and then a larger line, below that a pair of fairly deep impressions, and below that another pair of single broad grooves, and then another pair, one of the lines is not in the same size, and then as one gets further down the match is—the bullets are no longer in a match relationship, simply because Q-1 is somewhat distorted as a result of having struck some hard object at the base portion, so that it is oval.
In the case here we are comparing two surfaces of different radii so that they do not—looking at them as a projection they do not match up.
But in this particular region, from approximately this fill-in in the cannelure, there is a sufficient number of points of identification to lead me to the conclusion they were both fired in the same weapon.
Mr. Eisenberg. Could you mark that, that you mention as "2"?
Mr. Dulles. This again, at least the "Q" part of this, is the bullet that was found in the stretcher?
Mr. Nicol. Yes, sir; this specimen here.
Mr. Dulles. That is on the left-hand side, is it?
Mr. Nicol. Yes, sir.
Mr. Eisenberg. "Q," as Mr. Cunningham stated, is the FBI mark for "questioned," whereas "K" is the FBI mark for "known."
Mr. Nicol. I retained the same nomenclature so I would not add any unnecessary marks.
