The post office box to which the rifle was shipped was rented to “Lee H. Oswald” from October 9, 1962, to May 14, 1963.[C4-14] Experts on handwriting identification from the Treasury Department and the FBI testified that the signature and other writing on the application for that box were in the handwriting of Lee Harvey Oswald,[C4-15] as was a change-of-address card dated May 12, 1963,[C4-16] by which Oswald requested that mail addressed to that box be forwarded to him in New Orleans, where he had moved on April 24.[C4-17] Since the rifle was shipped from Chicago on March 20, 1963, it was received in Dallas during the period when Oswald rented and used the box. (See Commission Exhibit No. 791, p. 120.) [Illustration: DOCUMENTS ESTABLISHING PURCHASE OF RIFLE BY LEE HARVEY OSWALD COMMISSION EXHIBIT 791 APPLICATION FOR POST OFFICE BOX COMMISSION EXHIBIT 773 PURCHASE ORDER COMMISSION EXHIBIT 788 MONEY ORDER WALDMAN’S EXHIBIT 7 KLEIN’S SHIPPING ORDER] It is not known whether the application for post office box 2915 listed “A. Hidell” as a person entitled to receive mail at this box. In accordance with postal regulations, the portion of the application which lists names of persons, other than the applicant, entitled to receive mail was thrown away after the box was closed on May 14, 1963.[C4-18] Postal Inspector Harry D. Holmes of the Dallas Post Office testified, however, that when a package is received for a certain box, a notice is placed in that box regardless of whether the name on the package is listed on the application as a person entitled to receive mail through that box. The person having access to the box then takes the notice to the window and is given the package. Ordinarily, Inspector Holmes testified, identification is not requested because it is assumed that the person with the notice is entitled to the package.[C4-19] Oswald’s use of the name “Hidell” to purchase the assassination weapon was one of several instances in which he used this name as an alias. When arrested on the day of the assassination, he had in his possession a Smith & Wesson .38 caliber revolver[C4-20] purchased by mail-order coupon from Seaport-Traders, Inc., a mail-order division of George Rose & Co., Los Angeles. The mail-order coupon listed the purchaser as “A. J. Hidell Age 28” with the address of post office box 2915 in Dallas.[C4-21] Handwriting experts from the FBI and the Treasury Department testified that the writing on the mail-order form was that of Lee Harvey Oswald.[C4-22]
