The KDF car never went into production as the Beetle we know as WWII kicked off, and the factory went over to miltary production of the Kupelwagen and Schwimmwagen. Hirst, a British Army officer was put in charge of clearing up the mess at the factory, and decided to put together some of the KDF cars, which the British Army placed orders for in their thousands. Part of Hirst's equipment for shifting stuff around the factory were Army fork lifts, but unhelpfully they were absconded by another department.
Someone came up with the idea of creating a platform with and engine and steering at one end to replace the forklifts, and the vehicle ultimately developed into the Type2 initially using the flatbed chassis of the car. This proved disastrous, as the car chassis would fracture, so a new chassis was developed. All this was aided and abetted with the larger than life Dutch business man Ben Pon, who sketched out in a notepad something that looked like a loaf of bread, and the VW van was born.
Bet you didn't want to know that . . .
