The National Bulk Carriers was company set up by Daniel K. Ludwig to transport oil and bulk cargoes, mainly iron ore. The company was operating its ships either for charter, to companies like Amoco and Sinclair, and also for itself. Although the ships were registered in New York, its operations were mainly on the Delaware River.
Here is the T3 S BZ1 type tanker after WW2. Gone now are the guns, the life rafts as well as the upper aircraft deck used to carry aircraft as cargo from the US to Britain.
Thank you Kim for the crest
