Mr. FITHIAN. Mr. McCamy, can you give us any measurement or photogrammetric process or anything that you did to further nail down this I think vital question.
Mr. McCAMY. Yes. We made measurements, measurements on the rifle, and on the photographs to ascertain that indeed this particular chip was in the right place.
Beyond that, however, I went to the Archives and made 21 photographs of the rifle using a variety of different kinds of illumination. On those photographs, it was possible to see a large number of nicks, scratches and so on, distinguishing marks.
I then went back through all of the photographs I had mentioned to you. In many instances--I believe in 56 different instances--I was able to find markings that appear on this rifle that were on the photographs that were made back there on the day of the assassination.
So, we are very confident that this is indeed the rifle that was carried from the book depository--oh, incidentally, I can carry it farther than that.
I found distinguishing marks of this rifle on a motion picture that was made at the time the police officer picked the rifle up off of the floor of the book depository. So that I think is very convincing evidence that it is the rifle.
