Mr. KELLEY. The car that was used was a 1956 specially built Cadillac, open, a convertible, seven-passenger Cadillac. It has a termination of 679-X, the Secret Service calls it. It is a car that is used as a followup car to the President's car when he is in a motorcade. Mr. SPECTER. Was that car actually in the motorcade on November 22, 1963, in Dallas? Mr. KELLEY. Yes; it was. Mr. SPECTER. Was there any special reason why the car in which the President rode on November 22 was not used? Mr. KELLEY. Yes; the car in which the President rode has been modified by a body builder in Cincinnati, the Hess & Eisenhardt Co. of Cincinnati. Mr. SPECTER. And do you have a diagram showing the dimensions of the Secret Service followup car which was used during the onsite tests? Mr. KELLEY. I have. It was felt that the best simulation of the test could be presented by having a car that was similar to the car in which the President was riding, which was also an open Lincoln convertible. Mr. SPECTER. May it please the Commission, I would like to mark the diagram of the followup car as Commission Exhibit No. 871 and move its admission into evidence. The CHAIRMAN. It may be admitted. (The document referred to was marked Commission Exhibit No. 871 for identification, and received in evidence.) Mr. SPECTER. Do you have diagrams showing the dimensions of the Presidential car? Mr. KELLEY. I have. Mr. SPECTER. I would like to have that marked as Commission Exhibit No. 872 and move for its admission into evidence. The CHAIRMAN. It may be admitted. (The document referred to was marked Commission Exhibit No. 872 for identification, and received in evidence.) Mr. SPECTER. Without specifying all of the details, Inspector Kelley, are the followup car and the Presidential car generally similar in dimensions? Mr. KELLEY. Yes; they are. There are very few, of course, seven-passenger convertible cars in existence, and these are specially--these cars are specially built for us by the Lincoln--the Ford Motor Co. and the followup car by the General Motors Co. Mr. SPECTER. Would you describe what seating arrangements are present in each of those cars in between the permanent front seat and the permanent rear seat? Mr. KELLEY. There are two jump seats that can be opened up for riders in each of the cars. In the Presidential followup car, these jump seats are usually occupied by Secret Service agents. In the President's car, they are occupied by the President's guests. On the day of the assassination, of course, the jump seats were occupied by Mrs. Connally and Governor Connally. Mr. SPECTER. Mr. Kelley, have you brought with you two photographs depicting the interior of the President's car? Mr. KELLEY. I have. These are photographs of the interior of the President's car which is known to us as 100-X. Mr. SPECTER. May it please the Commission, I would like to mark one of these photographs as Commission Exhibit No. 873, and move its admission into evidence.
