Société Navale Delmas-Vieljeux — historical variants

The Nüsse-based design differs slightly and is placed nearer the hoist. A black-and-white photograph of Maurice Delmas confirms the related S16 funnel with the flag design. Stewart 1953 and 1957 show a narrow black funnel base, effectively a very broad blue band with the emblem at its top; Rosanoski considers this unlikely.

Exact dates, wheel shapes and shades remain qualified.
