A few days ago Mike Dean from England did send me very kindly a copy of some pages of the above German K.M. periodical of 1943
The main subject of this paper is on the Seehund IR apparatus. This code-name might be confusing because there existed also a Seehund type 127 midget submarine (two-man U-boat).
