4. Next In the film are a group of Codfish messages
which are sent for X setting and final solution. This circuit
uses Bream patterns but is not worked on at present because
of lack of time. The link is Berlin - Salonika. The plain
language characteristics were formerly about the same as
Berlin Bream. The circuit uses X2 and P5 limitatlons. The
message numbers, page lengths and encipherment dates are:-
#4691-47-Apr. 16, #5060-65-Apr. 25, #5099-43-Apr.26, #4998-
1-Apr. 23, #4999-33-Apr. 23, #1853-21-Apr. 26. All but the
last are from Salonika, the text of #5060 seems good only
for the first 40 odd paqes, In #5099 pages 16-41 seem to be
the beat stretch. It you wish to try 3 wheel runs or other
procedures adaptable to shorter messages selections of good
text of whatever length desired can be made from these messages.
#s 4998 and 4999 have the same QEP numbers and are on the
same date and can be used to practice derivation of Psi
patterns.

patterns for the dates covered by the above messages are as
