Summary  
The documents detail the handling of a magnetic tape recording obtained from STUS PRUSZYSKI by RMG's, which contains a garbled audio recording of events following an assault on Robert F. Kennedy (RPK) on June 8, 1968. The FBI Laboratory filtered two copies of the tape to improve intelligibility and reduce interference hum. The original and modified tapes were sent to the Los Angeles FBI office via registered mail. A separate laboratory report notes that analysis of Qc36 revealed recording inconsistencies due to non-standard equipment use, and a copy was provided to the Los Angeles Police Department for review. The LA office concluded the tape contained no pertinent information related to the investigation. Technical details of the tape include its original recording on a battery-powered telephone recorder at 3 1/4 IPS, duplication on Huar'n 1000 Mode-1 equipment, and manufacture by Audio Devices, Inc.
