Mr. STOMBAUGH. I removed fibers from the shirt to determine the composition of it and also the colors. I found that the shirt was composed of dark-blue, grayish-black, and orangish-yellow cotton fibers, and that these were the same shades of fibers I had found on the butt plate of the gun. Mr. DULLES. Did you find all three shades? Mr. STOMBAUGH. All three shades; yes, sir. Mr. EISENBERG. All three shades were found on the fragments that were found in the butt of the gun? Mr. STOMBAUGH. Yes. Mr. EISENBERG. Have you made photographs showing these, color photographs showing these? Mr. STOMBAUGH. Yes, sir. Color photographs are very difficult to make microscopically because the color isn't always identical to what you see in the microscope. So these colors are slightly off. Mr. EISENBERG. You have shown a chart captioned "Microphotograph Showing Match Between Orange-Yellow Cotton Fibers From Butt Plate of Assassination Rifle and Orange-Yellow Cotton Fibers From Oswald's Shirt." Did you take this photograph? Mr. STOMBAUGH. No; it was taken under my supervision. Mr. EISENBERG. It was taken under your supervision. Mr. Chairman, may I submit this as 674. Mr. DULLES. It will be admitted, 674. (The item referred to was marked Commission Exhibit No. 674, and was received in evidence.) Mr. EISENBERG. What is the magnification? Mr. STOMBAUGH. I believe this was 400 also. I am not certain of this, because the shot itself has also been enlarged. Mr. EISENBERG. Now you were discussing the reproduction of the color in the photomicrograph? Mr. STOMBAUGH. Yes, sir. These are the orangish-yellow fibers. The color is not exactly the same as what one would see under the microscope. However, you can see that the fibers on both sides, namely, the fiber from the rifle here, and this---- Mr. DULLES. On the right-hand side---- Mr. STOMBAUGH. On the right-hand side. Mr. DULLES. Of Exhibit 674? Mr. STOMBAUGH. And the fibers from the shirt, which are on the left-hand side of Exhibit 674, do match. The colors are the same and also, we find the same twist in the fiber. Mr. EISENBERG. Now, was the orange-yellow cotton fiber--were the orange-yellow cotton fibers in the shirt of a uniform shade? Mr. STOMBAUGH. Yes; they were all of a uniform shade. It was what we would call a uniform dye job. Mr. EISENBERG. What about the twist? Mr. STOMBAUGH. The twist was about normal. These, you can see here. Mr. EISENBERG. You are pointing to the right-hand side and left-hand side of 674? Mr. STOMBAUGH. You can see the twist to these fibers. Mr. EISENBERG. Did they have a uniform twist? Mr. STOMBAUGH. Uniform. Mr. EISENBERG. So that the match was identical as to twist and shade, and the fibers in the shirt were uniform in themselves as to these two characteristics, is that correct? Mr. STOMBAUGH. Yes; that is correct. Mr. EISENBERG. Did you take a photograph of the gray-black cotton fibers?
