More likely it would have been Wilhelm Tranow's people at the Beobachtungs-Dienst ("Observation Service", commonly called B-Dienst for short). That was the service that intercepted, decoded, and distributed solutions of such things as the British Naval Cypher (which, by the way, was a code, not a cipher). They also broke the 'BAMS' code, the code the British used to coordinate shipping movements globally. At least, up until the British were able to change it to a more secure code after they figured out the Germans were reading their mail by breaking the Naval Enigma.
An example, given in David Kahn's book "Nazi Spies" says that on October 30th, 1942 B-Dienst decrypted a British message stating that convoy SC107 would steer a course of 45 degrees from it's then current location off of the tip of Newfoundland. Information like that would have even been transmitted for some of the individual ships sailing, since you have to coordinate your shipping to have it arrive at the proper port at the proper time in order to minimize bottlenecks.
The B-Dienst was reading that code well into 1943. So I just assume when I get a contact report on a map it came from B-Dienst. Of course, I might be biased towards assuming it was a SIGINT report, I was a dittybopper (Morse Interceptor) years ago. Also, since I haven't survived past November of 1942 yet, it hasn't been an issue for me
