Mr. Barnes. That is true.
Mr. Belin. Sergeant, I will ask you to examine Commission Exhibits Nos. Q-74, Q-75, Q-76, and Q-77, and ask you to state whether or not there appears to be any identification marks on any of these exhibits that appear to show that they were examined or identified by you?
Mr. Barnes. I placed "B", the best that I could, inside of the hull of Exhibit 74—I believe it was Q-74 and Q-75, as you have them identified.
Mr. Belin. Now all four of these exhibits appear to be cartridge case hulls, is that correct?
Mr. Barnes. .38 caliber.
Mr. Belin. .38 caliber pistol?
Mr. Barnes. Yes.
Mr. Belin. They are kind of silver or chrome or grey in color? You can identify it that way?
Mr. Barnes. Yes.
Mr. Belin. How many of these hulls, to the best of your recollection, did you identify out there?
