International Loadstar

The International Loadstar is a series of trucks that were produced by International Harvester from 1962 to 1978. The first purpose-built medium-duty truck designed by the company, International slotted the Loadstar between its light-duty pickup trucks (initially the C-series, later the D-series) and the heavy-duty R-series. Following the discontinuation of the latter, the Loadstar became the smallest International conventional, slotted below the Fleetstar and Transtar conventionals.

Produced primarily as a straight truck, the Loadstar was developed primarily for applications such as local delivery, construction, and agriculture. Along with fire truck applications, the Loadstar was offered as a "Schoolmaster" cowled school bus chassis.

In 1978, International introduced the medium-duty S-Series, consolidating the Loadstar and Fleetstar into a single model family.
