The pattern is indeed Lotus, by W. & S. Sorensen of Horsens, Denmark. Brothers Winther and Sofus Sorensen founded Horsens SÃ¸lvvarefabrik in 1904, and I've seen the HS mark attributed to that company, but haven't been able to verify it. Your silver is at least 826/1000 fineness, sterling would be 925/1000. My understanding is that silver production was reduced after the German occupation in 1940, but the Danish government had kept many of their industries going. Your latest date of 1943 fits in with the rise of the Danish resistance movement, which brought labor strikes (with resulting economic effects), active sabotage, and general unrest.
