So I’ve had this car on the back of my mind for a while and thought i’d share my thoughts.
From what I can tell, the company isn’t “ROO Hydraulic Equipment.” If you squint your eyes hard enough you make out “ROC Hydraulic Equipment.” Their logo and their name correlates with “ROC Hydraulics” out of Wilsonton, Queensland, Australia. But I suspect that the car is just parked in the shop for looks/storage or that ROC had a minor part in developing the car.
I know that OP already mentioned that it couldn’t be a Buckle, but there’s just something about it that makes me say they could be related. Story goes that Bill Buckle and his team built a fiberglass prototype roadster in 1955 using parts from a Ford Zephyr. If I had to say which parts however, i’d definitely say headlights, wheels, and maybe the front and rear windows. To me, the car looks very prototype-y, but I very well understand what makes it not look like a Buckle.
As for the sign in the window, it’s definitely either “RodWell” or “RodWall”, then it could either be “GT” or maybe even a year. Thanks to 727 for deciphering some of it, You can also make out “FIBER GLASS” which reinforces my Buckle theory, but as for everything else it’s all just unintelligible. Maybe RodWell/Wall was the name of someone related to the Buckle project and Bill Buckle just gave them the prototype for them to have/modify but I digress. This car is still one huge rabbit hole, and I hope the info I gave helps!
