Mr. Redlich was on the street with the car. At the car on the street were the occupants of the car, the Secret Service driver, Mr. Hickey, an agent from the FBI, who handled radio contact with control, Agents Anderton and Williams in the President's and Connally's seats, Mr. Gauthier and his aids, a surveyor, and I, were all on the ground in the vicinity of the car. Agent Frazier was in the window of the Book Building at the control point with the rifle that was found at the window following the assassination. Mr. SPECTER. Now, was that rifle found at the window or in another location on the sixth floor? Mr. SHANEYFELT. In another location on the sixth floor. Mr. SPECTER. And that is the Mannlicher-Carcano rifle which was heretofore identified as Commission Exhibit No. 139? Mr. SHANEYFELT. That is correct. Mr. SPECTER. And where were you positioned on most of the occasions at the time of the onsite tests? Mr. SHANEYFELT. For the first portion of them, I was at the car in the street, and at the position of Mr. Zapruder, the position from which he took his pictures. Mr. SPECTER. What communications were available, if any, among the participants at the various locations heretofore described? Mr. SHANEYFELT. We had radio contact between all points. Mr. SPECTER. What was the starting position of the car at the most easterly position on Elm Street, immediately after turning off Houston Street? Mr. SHANEYFELT. The first position we established that morning was frame 161. Mr. SPECTER. Was there not a position established prior in sequence to frame 161, specifically that designated as position A? Mr. SHANEYFELT. That was actually established later. But the first one to be actually located was 161. And we went back later and positioned point A. Mr. SPECTER. Well, let's start with the position which is the most easterly point on Elm Street, which I believe would be position A, would it not? Mr. SHANEYFELT. Yes. Mr. SPECTER. Have you a photographic exhibit depicting that position? Mr. SHANEYFELT. Yes; in each of the positions that we established, we used, insofar as possible, the Zapruder pictures to establish the position, or we established it from the window, and made photographs from the position Mr. Zapruder was standing in. Mr. SPECTER. This chart has been marked as Commission Exhibit No. 886. (The document referred to was marked Commission Exhibit No. 886 for identification.) Mr. SHANEYFELT. This shows the photograph that was made from the point where Zapruder was standing looking toward the car, and is a point that we have designated as position A because it is in a position that did not appear on the Zapruder film. The Zapruder film does not start until the car gets farther down Elm Street. Mr. SPECTER. What is that exhibit number? Mr. SHANEYFELT. Exhibit No. 886. Mr. SPECTER. And why was that location selected for the position of the car?
