Delmas — later variants

A reported 1989 change to the wheel’s teeth may concern the straight-sided outer spokes seen in a 2005 company-website funnel photograph. Rosanoski uses that photograph for D289 as a probable modern version, with flag blue assumed to match the funnel. The date and precise shade remain uncertain: straight-sided teeth already appear in a 1961 source, while an earlier website funnel image has angled teeth. Candeias’s dark-blue flag follows repeated use in Publico’s Carga e Transportes supplement; he suggests the shade may be flexible in marketing. Sache also notes white trucks and containers with an inverted blue logo.

Exact dates, wheel shapes and shades remain qualified.
