Thiess Toyota advertisement, 1978.
The photo shows a Land Cruiser in it's proposed army spec. Of interest is the design of the brush bar. It appears to be a modified S3 brush bar with more rounded top corners. The bar is straight (as per S3) whereas the bumper has rearward returns at each end. You can see from the close up photo that the final production brush bars were designed specifically for the Land Cruiser bumper and headlight settings etc.
