Mr. Shaneyfelt.

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.
Distance to the rifle in the window is 265.3 feet. The angle to rifle in window is 15°21' and this is based on the horizontal.
Distance to the overpass is 260.6 feet, the angle to the overpass is 1°28'.

Mr. Specter.

What would the angle be considering the adjustment on the angle of the street?

Mr. Shaneyfelt.

It would be less 3° or 12°21', approximately.

Mr. Specter.

When you say approximately is that because the adjustment is somewhat greater than 3°?

Mr. Shaneyfelt.

Yes.

Mr. Specter.

How much is it exactly, if you know?

Mr. Shaneyfelt.

It is 3.9. It is almost 4.

Mr. Specter.

Three degrees nine minutes?

Mr. Shaneyfelt.

Three degrees nine minutes, I am sorry.

Mr. Dulles.

Would you have to make a similar adjustment to the overpass?

Mr. Shaneyfelt.

Yes; because the angle to the overpass is based on the horizontal. The overpass, you would have to add the 3°9'.

Mr. Dulles.

From the overpass, is this an angle up or angle down?

Mr. Shaneyfelt.

This is an angle down.

Mr. Dulles.

So it is an angle down in both cases?

Mr. Shaneyfelt.

That is correct.

Mr. Specter.

When you say that you are reducing the angle of 15°21' by to an angle of 12°12', is that as the shot passes through the body of the President?

Mr. Shaneyfelt.

That is correct. It is at that point.

Mr. Specter.

How was the speed of the camera ascertained, Mr. Shaneyfelt?

Mr. Shaneyfelt.

We obtained from Mr. Zapruder, Mr. Nix, Mrs. Muchmore; their cameras for examination, and in the FBI laboratory exposed film in all three cameras, aiming, focusing the camera on a clock with a large sweep-second hand. We then ran the camera at the speed and conditions as described by the people who used the cameras. We ran through several tests of film, and then after the film was developed it was studied under magnification, and frames were counted for a period of 2 to 3 seconds or for the full running time, and averages were taken.
Mr. Zapruder has stated that his camera was fully wound. Most of the others have stated their cameras were fully wound, so we were able to more or less eliminate the very slow time that occurs when the cameras are approximately run down, and all of these things were taken into consideration and were averaged.
The Zapruder camera was found to run at an average speed of 18.3 frames per second.
The Nix and Muchmore cameras were both found around 18.5 frames per second.

Mr. Specter.

Were you able to ascertain the speed of the Presidential limousine at the time of the assassination?

Mr. Shaneyfelt.

Yes; because we were able to determine the speed of the camera, and thereby accurately determine the length of time it takes for a
