RNAS crews are treated as independently recreating an armed vehicle to solve the immediate problem of rescuing colleagues. They were probably unaware of Simms's earlier designs. The retelling starts with an unarmored car and adds protection only after repeated dangerous trips. Details remain variable: the car is usually called a Rolls-Royce and occasionally a Bentley, while the means of attaching the first gun is uncertain. This different starting problem explains why the early Motor Scout and wartime armored car receive separate places in the list.
