Cool picture of D-20 and D-30 of the Blue Band Escadrille, a display flight. This name, with the English words, was likely unofficial, Blue Band being a margarine brand. Twenty D.VIIs served with the Dutch navy. Note headrests, fitted from 1925. Photo from: Nederlands Instituut voor Militaire Historie
