I just got a Photo etch set for the Russian battleship Borodino (battle fo Tsushima-1905).
The set includes porthole frames, and says they were left unpainted on ships of the period. Now, the graphic on the instruction sheet shows the ship in wartime colors.
I know ships of dawn of twentieth century were often painted in an attractive white and buff color, and I can see those ships with lots of unpainted brass.
But I am painting ship in wartime very dark grey. It seems unlikely to me that the brass would have been left unpainted with such a paint scheme. what do folks think?
