A picture is available on this external page (click in it to enlarge).

Tonnage: 925 displ. t.

Built bu Harland & Wolff Ltd., Belfast in 1941.

5 British built Flower class corvettes were taken over by the Norwegian Navy in Gt. Britain. They were Montbretia, Eglantine, Acanthus and Rose in 1941, and Potentilla in Jan.-1942. The Norwegian navy was to be responsible for supplying the crews, their salary, food and uniforms, while other expenses were to be paid by Royal Navy. They were used as escorts in the North Atlantic and carried out over 80 attacks against U-boats. When Potentilla was returned to Royal Navy in March of 1944, it was replaced by a Castle class corvette, which was named Tunsberg Castle under the Norwegian flag. Buttercup, also Flower class, was transferred after the loss of Tunsberg Castle in 1944. Follow the links for details on each corvette.

Jan-Olof has told me that according to Lenton & Colledge she became mercantile Nordkyn in 1946, Thoris in 1957 (Thor Dahl whale catcher). According to a posting to my Ship Forum she was handed over first to RBN (Belgian Navy) in Febr.-1942, then in Dec-1944 became Nordkyn(?) for the Norwegian Navy and purchased by same in 1946, pendant F 309. Axel Kuehn, the poster of this message adds that the 1946 sale might have been reported erroneously as a civilian sale (which might explain Lenton & Colledge's entries). I've only seen this corvette referred to as Buttercup, not Nordkyn, in Norwegian books. See also my query which has several responses. This one might also be of interest.
Atle Wilmar, Norway has given me the following dates:
Came under Norwegian command in Liverpool on Dec. 20-1944, "ready for war" Febr. 15-1945. After the war was over in Norway, she arrived Oslo on May-15-1945, purchased in 1946, renamed Nordkyn on Aug. 10-1946.
