Talk:German submarine U-31 (1936)

The picture and acronyms
On clicking the photograph, I find that underneath the 'permission' box somebody has stated that the picture is a) not U-31), b) probably not taken at Lorient and c) "1940 is also unlikely". Unfortunately, these comments are anonymous, but if the picture is so inaccurate, why keep it?

Some unexplained acronyms are on the article page; i.e. 'BRT', NO' and 'FO'. I am fairly sure that 'BRT' is "Brutto (Gross) Registered Tons"; but 'NO' and 'FO'? 'Something' "Office" maybe? (But I don't think 'FO' is 'Foreign Office' in this context). If anyone knows, would they please add some pearls of wisdom to the page?

U-31
Certainly U-31, because this man Wilhelm Tranow a cryptanalyst with the B-Diesnt, the naval intelligence organization and it was his work that dispatched the sub at the beginning of the war. I've just linked the two articles. Found this []. Seems there was only 35 men on it. It must have been hellish, cramped and claustrophobic. scope_creep 10:35, 13 August 2016 (UTC)
