And the instant that he could first see that chalk mark is the point where he radioed to us to stop the car, and is the first point at which a shot could be fired that would go in where the chalk mark is located. Mr. DULLES. And that is point A? Mr. SHANEYFELT. That is point A. Does that answer your question? Representative FORD. I think it does. Is that picture in the lower left-hand corner of Exhibit No. 886 an actual photograph taken through the sight of the weapon that was allegedly used in the assassination? Mr. SHANEYFELT. That is correct. Representative FORD. And the chalk mark we see there is through that sight? Mr. SHANEYFELT. That is correct. And that is exactly what an individual looking through the sight would see. Mr. SPECTER. Then at point A, could the rifleman see the entire back of the President's stand-in as well as the specific chalk mark, as depicted on the exhibit? Mr. SHANEYFELT. He could see only a portion of the back. Mr. SPECTER. And the portion, which he could not see, is that which is below the seat level? Mr. SHANEYFELT. Yes. Mr. DULLES. You didn't say the President's stand-in, did you? Mr. SPECTER. Yes; stand-in. Mr. Shaneyfelt, for purposes of illustration would you produce the photograph at this time showing the mounting of the motion picture camera on the weapon found on the sixth floor? I now hand you a photograph which is being marked as Commission Exhibit No. 887 and ask you to state for the record who that is a picture of, and what else is in the photograph. (The document referred to was marked Commission Exhibit No. 887 for identification.) Mr. SHANEYFELT. Commission Exhibit No. 887 is a picture of me that was taken on May 24, 1964. My location was at the sixth floor window of the Texas School Book Depository that we have designated as our control point. I have the rifle that is the assassination rifle mounted on a tripod, and on the rifle is mounted an Arriflex 16-mm. motion picture camera, that is alined to take photographs through the telescopic sight. This Arriflex motion picture camera is commonly known as a reflex camera in that as you view through the viewfinder a prism allows you to view directly through the lens system as you are taking your photographs so that as I took the photographs looking into the viewfinder I was also looking through the scope and seeing the actual image that was being recorded on the film. Mr. SPECTER. Was the view recorded on the film as shown on Exhibit No. 886 the actual view which would have been seen had you been looking through the telescopic sight of the Mannlicher-Carcano itself? Mr. SHANEYFELT. Yes. Mr. SPECTER. How did you determine the level and angle at which to hold the rifle? Mr. SHANEYFELT. I placed the rifle in the approximate position based on prior knowledge of where the boxes were stacked and the elevation of the window and other information that was furnished to me by representatives of the Commission.
