Hi Simonwp. They were my favourite type of ship for a long time when I first saw them in the early eighties. Nigerian National Line, Yugoslavian built and one of the series was for many years under arrest in antwerp , or deserted by its owners ( I do not know which). When if finally departed Antwerp it was under tow from a tug which sailed straight to the breakers with her.
Correct me if I am wrong?

Regards Frank
