I like colliers and I love ships with goalpost masts, so I'm pretty much in heaven now.
The derricks look wonderful-what ship parts did you use to get that "X" shape?
I've tried to find more information on the "Nereus" and "Proteus", but there isn't all that much, even on the 'net. Their loss isn't very surprising; they would have been in their 20's and 30's by the outbreak of WWII, and I think you said earlier that this class of ships wasn't particularly well maintained. Bad weather, bad rust, and a stressed, 30-y/o hull full of heavy ore-NOT a good mix.
IIRC there was an important chairperson of a certain company (Canada Steamship Lines?) who died in one of the sinkings.
