Mr. Specter.
Are the photographs and measurements on 896 the same layout as those affixed to prior exhibits?

That is correct.
Mr. Specter.
Was the automobile stopped at frame 235 and similar photographs and measurements taken?
Mr. Shaneyfelt.
That is correct.
Mr. Specter.

And what Commission exhibit number is given to those calculations and photographs on frame 249?
Mr. Shaneyfelt.
Commission Exhibit 899.
Mr. Specter.
Now, as to frame 249, that is how many frames beyond the first point at which the spot on President Kennedy's back was visible after he passed out from under the oak tree?
Mr. Shaneyfelt.
That is 249?
Mr. Specter.
Yes.
Mr. Shaneyfelt.
It is 42 frames.
Mr. Specter.
And does a 42-frame count have any significance with respect to the firing time on the Mannlicher-Carcano rifle?
Mr. Shaneyfelt.
Yes; we have established that the Zapruder motion picture camera operates at an average speed of 18.3 frames per second. And we have been advised that the minimum time for firing the rifle in successive shots is approximately two and a quarter seconds. So this gives us then a figure of two and a quarter seconds of frames; at 18.3, this gives us this figure of 41 to 42 frames.
Representative Ford.
Would you repeat that again, please?
Mr. Shaneyfelt.
The camera operates at a speed of 18.3 frames per second. So that in two and a quarter seconds it would run through about 42--41 to 42 frames.
Representative Ford.
Then the firing of the rifle, repeat that again?
Mr. Shaneyfelt.
As to the firing of the rifle we have been advised that the minimum time for getting off two successive well-aimed shots on the rifle is approximately two and a quarter seconds. That is the basis for using this 41
