Trojan began manufacture of small "parcel vans" in the early 1920's, these proved very popular with sales exceeding those of cars throughout the inter-war period. Trojan would custom-make bodies and livery of any design to order. They even made a van in the shape of a teapot with the exhaust vented through the spout. The basic van changed little through this period apart from the brief appearance of the Trojan "Senior" van, which was a forward controlled van. Trojan also experimented with a six wheeler designed for the army, but these never went into production.
