The Spanish Military Attaches and the Spanish Naval Attaches
apparently are equipped with Enigma machines with three
single-notch wheels, a movable reflector, a fixed QWERTZU
input sequence and enigma stepping. Present techniques on
bombes and hypo were satisfactory about eight months ago when
a new key list went into effect. Since January 1, 1945,
traffic has vanished to practically nothing. In the past,
poor cryptographic usage of the Naval Attache Machine has en-
abled the recovery of the wheel wirings from scratch. (Bri-
tish).
There is reason to believe that some years ago the Swiss Gov-
ernment acquired some of the commercial enigma machines with
three single-notch wheels, a movable reflector, a fixed
QWERTZU input sequence, and enigma steppinge About every two
years (this time limit is a guess) the Swiss rewire the three
movable wheels. Present techniques on bombes and hypo units
are satisfactory for reading current traffic. In the past,
poor cryptographic usage has enabled the recovery of wheel
wirings from scratch. (Coast Guard and probably U. S. Army).
lately this problem has been a U. S. Army Signal Corps problem.
In the past the Coast Guard has worked on German Agent Systems
with three single-notch wheels, a movable reflector, a fixed
QWERTZU input sequence and enigma stepping. In the summer of
1944 there was some traffic in a system employing the first
three so-called service wheels and a variable reciprocal in-
put sequence. In all of these cases, however, present opera-
tional equipment and procedures have been sufficient to read
the traffic.
