Lundgren’s flag resembles Börjesson’s yellow flag with a blue shield and yellow disc, but carries a blue S instead of A. US Navy 1961 attributes L81 to Sigyn.
The combined livery is recorded for Silken in 1957–63 under Lundgren & Börjesson, although Lloyds lists Hans Lundgren. NJK’s funnel and Bakker’s Bryggan-based flag give green letters; the US Navy’s Alfa Sigyn attribution and the Collectors Corner cap badge give blue. Rosanoski considers the apparent green an optical effect of blue over yellow. The merger and the colour interpretation remain distinct questions.
