I have recently acquired a workshop full of parts and tools including an old Car-o-liner style tool which I believe is for straightening chassis. It consists of one long red steel beam with a couple of wheels at one end, and a bunch of other items which were in the workshop and I believe are associated, including a hydraulic piston, chains and various steel attachments. Does anyone recognize this vague description? Can you tell me how it works? What are the attachments? Are there any websites with details? Anything constructive would be appreciated.
