Good question Pieter, but I suspect not. I hope that a Polish expert will be able to clarify. This ship was the second of the B50 type. The first, NOWA HUTA, was launched as WARSZAWA and entered service as such in October 1952. KOPERNIK was delivered in July 1953 while the third seems to have been cancelled. The fourth and fifth, GDYNIA and SZCZECIN, were completed at Aarhus, entering service in July 1953 and November 1953 respectively. (Information from Miramar)

Good shot Malcolm, did she ever trade as Lodz?
