I won't duplicate the thread here, but I'm in the process of restoring a 1950s floor or service jack that belonged to either my dad or my uncle. It probably hasn't been disassembled for 40 years (if ever). It's fully functional again, and late this fall, I will disassemble the frame, have it sandblasted and then I'll prime and paint it in original colors. You can see the details here Steve Bryant's Blackhawk Jack Thread - The Garage Journal Board. For a quick look at a larger picture, just click on the thumbnail below.
