WORK NOTICE BOOK.

This book furnishes a permanent file for notices affecting changes in

operation procedure. Such notices are usually put on the bulletin board for
about 3 days. After they have been initialed by all IC/OPS and it is
reasonably certain that all concerned are familiar with the changes, they
are pasted in the Work Notice Book.

TIME SHEET.

The Time Sheet is a record for all bombes and includes all time spent

on jobs from midnight of one day to midnight of the next. It is the
responsibility of the IC/OPS on the midnight to 8 a.m. shift (graveyard) to
prepare the time sheet. The information required is obtained from the
Control Log Book and the Daily Log. A sample time Sheet is shown in figure
43. It is used locally for the information of the watch officers. It is
also sent to the head of the Eastcote Outstation for transmission to
Bletchley Park, Hut 6 Statistics. Major Manisty uses the information on the
Time Sheet for the allotment of bombes.

TECHNICIANS BULLETIN BOOK.

This book is a permanent file of notices covering changes in the

maintenance of the bombes. These notices are usually posted on the bulletin
board for Technicians and Engineers. After all Technicians have seen the
notice they are pasted in the Technicians Bulletin Book.

MACHINE FAULTS BOOK.

This book is used to record all the types of trouble encountered in

the maintenance or the bombes and the remedies necessary to clear the
troubles. The entries are made by the watch engineer and initialed by the
watch officer. Every trouble encountered is noted down. The book is
inspected by the watch officer once each day.

TOOL RELEASE SIGNOUT SHEET.

This is a sheet mounted inside the door of the tool cabinet and

serves to provide a running inventory of the tools in the cabinet. As each
watch engineer comes on duty he inventories the tools in the cabinet before
signing the sheet and releasing the previous watch engineer. Should there
be any discrepancies he notes these on the sheet before signing. The watch
officer on the day shift (0800 to 1730) each Saturday inspects the tool
cabinet and if any tools are found to be missing a Statement of Charges is
made to cover the cost of that tool and the money taken from the pay of the
watch engineer who last signed that all tools were in the cabinet.

TOOL CHARGE BOOK.

In this book is kept a record of the tools loaned to the R.A.F. The

entries are made either by the watch engineer or a technician.

JOBS UP CHART.

This is a bar graph type chart kept on the wall of the IC/OPS room by

the IC/OPS. On it is plotted a record of the number of "jobs up" in USA Bay
against day of the month. On each unit of the bar graph the letter
designation of the "watch" responsible for the job is recorded.

NOTES TO WATCH OFFICERS BOOK.

This book consists of a notebook divided into six sections, one each

assigned to each watch officer, one for the special officer and one for
general information. This book serves to transmit information between
officers and for individual officers to keep memoranda of important items.

SUPPLY BOOK.

This book provides for entering requests for supplies. The person

needing the supplies notes the items desired and signs his name and the
date. These requests are approved by the signature of the OIC and when
sufficient items are accumulated
