House flag of Somers
Duwvaart, by Jansen & Van Heck, positions Somers as a precursor of Somtrans. Somers, then based at Kapellen to the north of Antwerp, is presented and its flag is shown in black and white, as white, with red horizontal edges and a green lozenge or diamond bearing a white S in the centre. The illustration gives the broad middle white stripe half of the flag's height. The diamond is regular, not pulled out downwards as in Somtrans house flag.
