Compagnie Delmas Frères et Vieljeux / Delmas-Vieljeux — historical variants

C437 has a small square at the wheel’s centre and a larger wheel on the flag. The larger wheel continues in C438, later with a blue core. The FOTW rendering of C437 also has a blue core and follows information from a Sandy Hook poster for Medea, about 1920.

Exact dates, wheel shapes and shades remain qualified.
