Mr. Cadigan. Klein's Sporting Goods Store in Chicago, from which the Italian rifle was bought.
Mr. Eisenberg. That is Exhibit 139?
Mr. Cadigan. Exhibit 139. The agent brought in these paper samples from Klein's for comparison purposes, and the paper tape, this manila gummed tape, had these knurl markings measuring 30 per inch.
Mr. Eisenberg. That is the gummed tape you obtained from Klein's?
Mr. Cadigan. Yes. It was not identical with this, but merely, you might say, illustrate that the markings will differ depending on the wheel, and if your wheel has 30 lines per inch and your other sample is 24 or 25 lines per inch, you know they didn't come from the same tape dispenser.
Mr. Eisenberg. Mr. Cadigan, do these wheels differ as to their diameter across the bearing surface, the length across the rolling knurled surface?
Mr. Cadigan. I imagine there would be a difference.
I have made no precise measurement but I imagine they vary within tolerances of a quarter- or half-inch in width.
Mr. Eisenberg. Would the length of the lines produced on 142 be the same—the paper bag—the same as the length of the lines produced on 677?
Mr. Cadigan. Yes.
