The Kalmar KVD440/441, also variously known as Tjorven or DAF Kalmar, is a delivery van based on the DAF 44, made in Sweden. The vehicle inherited the air-cooled, 844cc boxer engine and Variomatic transmission from the DAF 44. "Tjorven" was a nickname given to the Kalmar as its rather frumpy appearance was reminiscent of a contemporary Swedish television character of that name. It was RHD for easy driver access to road side letter boxes, frame-built with a fiberglass bodywork.
