My guess, and only a slightly educated guess, is an old Schaefer system. But with out the foils, top swivel, and connecting hardware that unit is a project that even if free will cost more than a new set up and considerably more than a used (yet complete) set up. My recommendation is to visit Defender, eBay, or one of the many other sites where equipment is available and find a complete setup sized appropriately. I will also say adding a proper furler is a wise decision that will increase your enjoyment on the water if you currently have a hank on sail setup (though they have their place).
