Santa brought a copy of Claes Sundin’s “Luftwaffe Bombers, Profile Book No. 7”. Gorgeous profiles, as usual, but two of them bear an overall blue finish with wave mirror squiggles.  The color is described as being RLM 83, Dunkelblau. A new one on me. Up until now I had thought RLM 83 to be one of two greens (dark or light, opinions seem to differ) used with RLM 81, so described by virtually every Luftwaffe colors source. I think I have them all starting with the Karl Reis books.   Sund
