What happened with the Walker bullet? Supposedly that was marked by 
several people, from the DPD to the FBI.
ON THE BULLET. The heavily mutilated bullet.
The bullet in evidence is a copper-jacketed, lead-core bullet fired from a 
6.5 caliber Mannlicher-Carcano rifle. It is too mutilated to be traced to 
any particular rifle. The FBI investigated the chain of possession of the 
bullet designated Q188. They reported it was found by Officer Billy Gene 
Norvell. As per routine procedure, he scratched his initial or initials -- 
either "BN" or just "N" -- onto the bullet's surface. Norvell handed the 
bullet over to B. G. Brown of the DPD's Crime Scene Search Section. Brown 
marked the bullet either "B" or "BB." On April 25, 1963, Lt. J. C. Day, 
the head of the Identifications Bureau, marked the bullet either "JD" or 
"D," and transported it to the City/County Investigation Laboratory and 
turned it over to F. T Alexander ("FA" or "A") and Louie L. Anderson ("LA" 
or "A"). On December 2, 1963 (when it was deemed relevant to the 
assassination), Day retrieved the bullet and gave it to FBI Special Agent 
Bardwell Odum ("BO" or "O"), who forwarded it to the FBI Laboratory, where 
it was initialed "RF" by FBI weapons expert Robert Frazier and an 
unidentified "HJ" (see also CE 1953).
In June 1979, the FBI reported, "Identifiable marks were found inscribed 
on varying portions of the bullet itself. It must be understood that 
certain markings are clearly discernible, others admit of more than one 
interpretation, while others may be obscured by oxidation or otherwise." 
And in fairness, sixteen years is much, much longer than the standard 
procedures regarding the handling of evidence are expected to encompass. 
That said, the markings found were "Q 188," "HJ," "RF," "N," "B," "J," 
"A," and a character that is either "D" or "O." The bullet was contained 
in an original DPD evidence box, dated 4-10-63 and marked by "BGB," "Day," 
"HJ" and "RF" (Memo from J. Edgar Hoover, July 3, 1979, #621-17290-144).
And yet you say these guys could not mark CE399? In the second photo from 
the National Archives there is plenty of room on that side of the bullet 
for more initials. Why so different for CE399?
