Mr. EISENBERG. What Commission exhibit is that?
Mr. CUNNINGHAM. No. 598.
On the left of the hairline is our number C-47, the cartridge case. On
the right is a test from the C-15 revolver, which is Commission Exhibit
143. These also are breech-face marks in the base of the cartridge
cases.
On the right you can see the space between the primer and the base of
the cartridge case, and also the individual characteristic marks in the
primer.
Mr. EISENBERG. What is the magnification?
Mr. CUNNINGHAM. This is approximately 123-1/2 times.
Mr. EISENBERG. Congressman Ford, would you care for a discussion of
this?
Representative FORD. No. The one previously gave the basis.
Mr. CUNNINGHAM. Actually, this seems to be a slightly larger area. You
have again the same "railroad tracks," all up and down, going across
the two cartridge cases.
