Mr. Frazier, you have appeared before to testify, but will you at this juncture again give us the outline of your occupation and experience? Mr. FRAZIER. Yes; I am a special agent of the Federal Bureau of Investigation assigned to the FBI Laboratory, Washington, D.C. I work in the firearms identification unit in the laboratory, making examinations of firearms, bullets, the effects of bullets, trajectories, firing tests, powder pattern tests, and various other types of examinations. (At this point Senator Cooper left the hearing room.) Mr. SPECTER. Have you appeared heretofore before the Commission to testify about examinations which you have conducted of the clothing worn by President Kennedy, the clothing worn by Governor Connally, the examination of the Presidential limousine and certain ballistics information? Mr. FRAZIER. Yes; I have. Mr. SPECTER. Did you participate in the onsite tests at Dallas on May 24, 1964? Mr. FRAZIER. Yes. Mr. SPECTER. What was your position during most of the time of those onsite tests? Mr. FRAZIER. I was stationed at the window on the sixth floor of the Texas School Book Depository Building at the southeast corner of the building. Mr. SPECTER. How far was that window open at the time the tests were being conducted? Mr. FRAZIER. I estimated it as approximately one-third. It was somewhat less than halfway open. Mr. SPECTER. Is that the distance depicted on Commission Exhibit No. 492, which has heretofore been introduced in evidence? Mr. FRAZIER. Yes, sir. Mr. SPECTER. Is the distance open on that window about the same as that which you had it open at the time these tests were run? Mr. FRAZIER. Yes; I would say that this is very close. The window was placed according to information already furnished to the Commission as to how much it had been opened at that time. Mr. SPECTER. Did you handle the Mannlicher-Carcano rifle during the course of the onsite tests? Mr. FRAZIER. Yes, sir. Mr. SPECTER. The rifle previously identified as Commission Exhibit No. 139? Mr. FRAZIER. Yes, sir; I did. Mr. SPECTER. At what position--what was the basis for your positioning of that rifle during those tests?
