1939 Pennzoil Chevrolet Panel Truck. Panel trucks first appeared in the 1930's when Chevrolet built a van on a truck chassis. These typically featured a seat for the driver and passenger, a large cargo area behind, and windowless side panels for sign writing. This diecast metal model has opening front doors, and is a standout in the yellow, red, and black colours of Pennzoil. A nice heavy model. Approx. 19cm x 7cm x 8cm (7.5" x 2.75" x 3.25").
