Heinz W. Michaelis, office manager of both George Rose & Co., Inc., and Seaport Traders, Inc., identified records of Seaport Traders, Inc., which showed that a “.38 S and W Special two-inch Commando, serial number V510210” was shipped on March 20, 1963, to A. J. Hidell, Post Office Box 2915, Dallas, Tex. The invoice was prepared on March 13, 1963; the revolver was actually shipped on March 20 by Railway Express. The balance due on the purchase was $19.95. Michaelis furnished the shipping copy of the invoice, and the Railway Express Agency shipping documents, showing that $19.95, plus $1.27 shipping charge, had been collected from the consignee, Hidell.[C4-588] (See Michaelis Exhibits Nos. 2, 4, 5, p. 173.) Handwriting experts, Alwyn Cole of the Treasury Department and James C. Cadigan of the FBI, testified before the Commission that the writing on the coupon was Oswald’s. The signature of the witness, D. F. Drittal, who attested that the fictitious Hidell was an American citizen and had not been convicted of a felony, was also in Oswald’s handwriting.[C4-589] Marina Oswald gave as her opinion that the mail-order coupon was in Oswald’s handwriting.[C4-590] When shown the revolver, she stated that she recognized it as the one owned by her husband.[C4-591] She also testified that this appeared to be the revolver seen in Oswald’s belt in the picture she took in late March or early April 1963 when the family was living on Neely Street in Dallas.[C4-592] Police found an empty revolver holster when they searched Oswald’s room on Beckley Avenue after his arrest.[C4-593] Marina Oswald testified that this was the holster which contained the revolver in the photographs taken on Neely Street.[C4-594] Oswald’s Jacket Approximately 15 minutes before the shooting of Tippit, Oswald was seen leaving his roominghouse.[C4-595] He was wearing a zipper jacket which he had not been wearing moments before when he had arrived home.[C4-596] When Oswald was arrested, he did not have a jacket.[C4-597] Shortly after Tippit was slain, policemen found a light-colored zipper jacket along the route taken by the killer as he attempted to escape.[C4-598] (See Commission Exhibit No. 1968, p. 164.) At 1:22 p.m. the Dallas police radio described the man wanted for the murder of Tippit as “a white male about thirty, five foot eight inches, black hair, slender, wearing a white jacket, white shirt and dark slacks.”[C4-599] According to Patrolman Poe this description came from Mrs. Markham and Mrs. Barbara Jeanette Davis.[C4-600] Mrs. Markham told Poe that the man was a “white male, about 25, about five feet eight, brown hair, medium,” and wearing a “white jacket.” Mrs. Davis gave Poe the same general description: a “white male in his early twenties, around five foot seven inches or eight inches, about 145 pounds,” and wearing a white jacket.
