I just glommed onto this jack at an antique shop. It's seized up, at least to finger pressure. I didn't want to try sterner measures before consulting the GJ. I cleaned it up a bit with solvent and wire brush, and found that most of what I thought was rust was just dirt and the texture of the cast iron endpiece. I have a use for it if I can get it working; I'd appreciate any tips on disassembly if a hydro requires different techniques from ordinary tools. I've started off by applying WD40 and PB to all the threaded parts-gonna let it sit for at least a day or two.
Meanwhile, I'm curious as to what brand it might be. The closest jack I've found on GJ is an Autco, but it's not very close except in overall configuration. There's enough paint left on it to tell it was all red, except for the height adjuster which is white. I've posted pix of the markings I could find, hoping someone can ID it.
If I can't get it working, at least I only paid $10 for it.
