Agents of the FBI learned on November 22, 1963, from retail gun dealers in Dallas that Crescent Firearms, Inc., of New York City, was a distributor of surplus Italian 6.5-millimeter military rifles. When contacted, Crescent Firearms said that they had shipped the rifle with the serial number C2766 to Klein's Sporting Goods Co., of Chicago. On the morning of November 23, Klein's found the order coupon and shipping record, showing the rifle was ordered by and shipped to "A. Hidell" at post office box 2915 in Dallas, Texas. That box had been rented under the name of Lee H. Oswald. Oswald was carrying two forged identification cards with the name "Alek James Hidell" in his wallet at the time of his arrest.
