Mr. Specter. And what position is station C?
Mr. Shaneyfelt. Station C is on a line drawn along the west curb line of Houston Street in a direct line, and station C is at a point along that line that is in line with where the car would have turned coming around that corner. It is on a line which is an extension of the west curb line of Houston Street.
Mr. Dulles. Where is position A on that chart?
Mr. Shaneyfelt. Position A is here.
Mr. McCloy. That is before you get to the tree?
Mr. Shaneyfelt. Yes; he isn't under the tree yet.
Mr. Specter. And what occupant, if any, in the car is position A sighted on for measuring purposes?
Mr. Shaneyfelt. All of the photographs made through the rifle sight that are shown on the exhibit in the lower left-hand corner were sighted on the spot that was simulating the spot where the President was wounded in the neck. The chalk mark is on the back of the coat.
Mr. Specter. When you say that position A is the first position at which President Kennedy was in view of the marksman from the southeast window on the sixth floor of the School Book Depository Building, you mean by that the first position where the marksman saw the rear of the President's stand-in?
Mr. Shaneyfelt. That is correct.
