This question partly belongs in the ship models forum, but I felt better asking it here where it might get wider input...
Last year, Flyhawk models has released 1/700 kits of the BC's Derfflinger and Luetzow. The paint guide for both calls for the second funnel to be painted a dark red.
When I built the Derfflinger, I followed the instructions and felt that it gave the kit a unique look. Now I'm about to start Luetzow and am wondering about the funnel colour. The pictures I've found of her do not suggest any difference in the funnel colour - same for Derfflinger.
So....did they really sport a red funnel at any time, and if so, what was the rationale? One would think that would stick out like a sore thumb in the sights of enemy gunners!
