Ken:
Here's a thread on the LF Forum about the manufacturer history of Zone VI cameras. The thread was started by someone who had just bought a camera that, by the photos posted, looks exactly like mine. Mine is cherry, with silver nickel-plated hardware, not brass gold-plated, and without a bail back. Front has tilt, swing, and rise/fall, and rear has tilt and swing. What I believe to be the serial number is 267: it is embossed in the black hardware the holds the camera together, and there is a number 67 embossed on the top of the camera bed at the rear.
