The white funnel follows Bellona on 8 August 2005. A different Bellona funnel is catalogued under Mengwall as N507.
The later Castor was operated, managed and owned by A.E. Mengwall, succeeded by G. Mengwall. It may have been the same company as Pettersson’s: Lloyd’s first assigned a new number, then reverted to the earlier number in 1996–97. Its stated foundation date of 1953 conflicts with the 1950 transfer to Castor and precedes Mengwall’s stated 1967 foundation. Bellona appears from 1980–81 and was rebuilt before the 1996–97 listing; the company was later a one-ship subsidiary and then an operating company. Rosanoski notes apparently identical particulars for Bellona and the earlier Svanfjord but does not resolve the vessel or company continuity.
