Creo este post en busca de datos referentes al asunto, la informacion que he logrado obtener me da indicios que era un sobrenombre de las tripulaciones, la colonia que se dotaba a la kiregsmarine, en especial al arma submarina era el perfume 4711. Cito de la wikipedia:
During World War II Nazi Germany's Kriegsmarine (navy) issued vast amounts of 4711 perfume to the submariners of the U-Boat fleet. As there were limited facilities and few opportunities for bathing, the scent was to be used in an attempt to improve the odour aboard the vessel. Crew members typically didn't use much of it and would take home bottles as presents for mothers, wives or girlfriends.
Que opinais al respecto.
