Mr. Frazier. Yes; it was.
Mr. Eisenberg. And illustrates——
Mr. Frazier. Excuse me. The actual diagram was copied by me from a textbook, showing a diagrammatic view of how a telescopic crosshair ring is mounted in a telescope.
Mr. Eisenberg. This is a generalized diagram, rather than a diagram of the specific scope on Exhibit 139?
Mr. Frazier. Yes; it is. However, I have checked the scope on Exhibit 139 and found it to be substantially the same as this diagram.
Mr. Eisenberg. Mr. Chairman, may I have this admitted as 555?
Mr. McCloy. It may be admitted.
(The document referred to was marked Commission Exhibit No. 555, and received in evidence.)
Mr. Frazier. Commission Exhibit No. 555 is a diagrammatic drawing of the manner in which the crosshair ring is mounted in Exhibit 139, showing on the right-hand side of the diagram a circular drawing indicating the outer part of the tube, with an inner circle with a crossed line in it representing the crosshairs in the telescope.
There is an elevation-adjusting screw at the top, which pushes the crosshair ring down against a spring located in the lower left-hand portion of the circle, or which allows the crosshair ring to come up, being pushed by the spring on the opposite side of the ring. There is a windage screw on the right-hand side of the scope tube circle which adjusts the crosshair ring laterally for windage adjustments.
