I'd want a better source for this before adding it to the article, but p38 of European Axis Signal Intelligence in World War II: Volume 8, when talking about Oskar Vierling's move to Laboratorium Feuerstein in 1942, says A small group remained in the vicinity of Hannover in charge of Dr. Sennheiser, an associate who had purchased a part interest in that laboratory. There's a reference to TICOM report M-12 which doesn't seem to be online (yet?). Adam Sampson (talk) 15:08, 20 July 2023 (UTC)[reply]
