This appears to be a transcription by a second person of part of the message, to which some annotations have subsequently been added (‘B2’ and ‘F’ in the 5th line, and ‘HM’ in the entry for 2240). Although the paper has become brittle and some of the information at the bottom has been lost, it is possible to make out the words ‘Passed COIC[part of word or name missing] per secraphone’ and a date/time group that appears to end ‘5/12’ The date time group 1630H/5[remainder missing] appears on the bottom right hand corner.
