President's Commission on the Assassination of President Kennedy | 200 Maryland Avenue N.E. Washington, D. GC. 20002 ATTN: Mr. J. Lee Rankin General Counsel Dear Mr. Rankin: | Skilled eryptologists at NSA carefully examined the materials relating to the Lee Harvey Oswald case provided by the Warren Com- mission. The results are as follows: a, A detailed examination of the two dictionaries revealed no indication of their use for cryptographic purposes. b. In the correspondence, the Oswald Diary, and the other documert 5 examined there wers no evidences of the use of any type of cryptography, to include the use of an open code. c. Certain letters had been removed from pages 180 and 182 of the Russian novel, GLAZA KOTORYE SPRASHIVAYUT, "Questioning . Eyes." Eight letters had apparently been cut from page 152 as follows: Line 10 Line 11 Line 13 Line 16 Line 24 Line 26 Line 27 One letter had been removed from page 150; however no significance is attributed to the removal of this letter since it corresponds in exact ELECTROSTATIC REPRODUCTION MADE FOR PRESERVATION PURPOSES BY THE NSA ARCHIVES FGR REPLACEMENT OF A DETERIORATING MANUSCRIPT ITEM y

The sample is considered too small for any valid conclusions to bs reached as to the purposes for which the above noted letters were removed. It {s considered most unlikely that this process of letter removal has any cryptographic implication. - d. The Russian "Tourist" portable radio was examined for ‘cryptologic evidence. The radio appears to be & normal receiver and there was no evidence of its use for any other purpose. @. The names appearing in Lee's and Marina's address books were checked, No evidence of cryptologic implication was found, , - , Although the results of the examination of the materials provided by the Commission are essentially negative, further study of these materials will be made. If any results are obtained, the Commission will be advised, However, it is considered most unlikely that any~ thing beyond what is reported above will be discovered, Sincerely, GORDON A, BLAKE Lieutenant General, USAF ' Director -
