For this reason it was necessary to use the Nix film of the head shot and the Muchmore film of the head shot to establish this position in the road. The right-hand photograph represents frame 24 from the Nix film, and is the frame that depicts the shot to the head. We used Mr. Nix's camera and a print of this picture and stood in the previously determined position of Mr. Nix when he took his photographs, and had them roll the car down to a position so that the President's head was directly under the point where Mr. Zapruder is standing on the projection. Mr. SPECTER. You are describing the photograph on which side---- Mr. SHANEYFELT. On the--- Mr. SPECTER. Of the viewer. Mr. SHANEYFELT. On the upper left-hand side. Mr. McCLOY. I think you said right. Mr. SHANEYFELT. The upper left-hand photograph is the photograph from the--taken from the frame 24 of the Nix film. The photograph on the right, upper right, is the photograph taken at the reenactment from the position where Mr. Nix was standing. We then proceeded over to the point that we had established as the position of Mrs. Muchmore, and using frame 42, which is a frame in her film depicting the shot to the head, and using the steps and their relation to the President and the objects in the background in relation to the President as shown in this lower left-hand photograph, which is the Muchmore frame 42, we reestablished, we checked the position we had placed the car in, based on the Nix photographs, and found that it conformed and checked out as being in a closely accurate position. This is the basis used for establishing the position of the car. After we had established that, through the Nix and Muchmore films, we then checked it against the Zapruder photograph, which is the second from the top on the left of Commission Exhibit No. 902, frame 313, which shows the explosion from the top of the President's head. Just to the right of that second picture down from the right, is the photograph made at the reenactment from Zapruder's position. We know from studying the films that just two or three frames before frame 313 we can see a little bit of yellow along the curb, and this checks out because along this area of the photograph from the Zapruder position of the reenactment is a yellow strip. Mr. SPECTER. When you say this area you are referring to the yellow area which appears on the left-hand curb immediately to the rear of the simulated car? Mr. SHANEYFELT. That is correct, and this, therefore, checks out this as being a fairly accurate position for the car in frame 313. This photograph then, the third down on the left, is a photograph through the telescope of the rifle of the car positioned in frame 313. Mr. McCLOY. Would you read off those dimensions from that? Mr. SHANEYFELT. The dimensions from the surveyor on frame 313 of the distance from the wound mark on the President's stand-in to station C is 230.8 feet.
