agree, looks like a Walker 2 ton. Like this one; even has the same shape swivel pad with the corner nubs rebuild http://jaredsgarage.blogspot.com/2016/05/rebuilding-walker-2-ton-floor-jack-j.html
I'm guessing 60's or 70's by the slip-on hand grips and what appears to be an aluminum release knob on top. Earlier than that, jacks more than likely had contoured cast metal where the grips were. You might try contacting the guy that did the rebuild blog.
I'd have to agree with Walker. Most of them that size got blown out because someone tried to lift something way too heavy with them. They are big so they can reach under the vehicle easily without having to get down and fight them into position but not rated very high. Sure nice to slide under the axle or rear end of a proper weight rig and jack it without getting down on your knees to work the jack though.
It is a Walker for sure, made right here in Racine Wisconsin. The plant is long gone just like so many big names that were once headquartered here.
Hello, That old photo looks like the exact one we got from a friend in Los Angeles. It was the best gift that two teenage brothers could get. It made everything that needed a roll, a lift or extra support with jack stands easier to handle and feel safe. But, as we used it every day from 1958 to 1963, it more than saved us time and strains on the teenage bodies. Ours was a heavy duty model, a 4 ton black and silver painted model. It was fairly new when we got it and after many years of use, let it out of our sight for one weekend. That was a tragic one at that. A friend was working on his rear axle suspension of his 56 Chevy Bel Air Sedan. He had it jacked up with the hydraulic jack. But, being in a hurry, he did not put in the jack stands. Something happened and the jack deflated, severely injuring our friend. From that point on, the jack was sitting in our garage, not being used until 1975 when I sold it for a char-broiled hamburger and fries. I sold it to a friend with the stipulation of not using it unless it had jack stands (which he did) and to get the hydraulic system rebuilt and adjusted. Our thought was that the twisting round handle was not tight enough and with a slight kick with the foot, started to get loose and lose all pressure to a tragic ending. Jnaki But, for any hot rod/drag race builder, enthusiast or something that every garage needs is a good working, safe hydraulic jack. It has countless job applications and they are usually built like an iron fortress, unless you get a small version that would have a hard time lifting a side or front/rear of any car. YRMV At home in Long Beach, during our teenage days, we were spoiled with the addition of a rolling hydraulic Walker Jack. If any work was to be done under the hot rod, the black and silver Walker Hydraulic Floor Jack came rolling out. Ever lift a complete Chevy Positraction third member from the concrete up to the drop in place, trying to match the bolts at the same time, while laying on your back? The new hydraulic jack made removing and replacing the complete third member a "walk in the park"... No more strain, although, it did make me stronger while I had to lay on my back doing the work at 10 pm at night... YRMV
Walker for sure. I got a Hein Warner WS a few years ago that had a slow leak down. Not a bad deal for $30. bought a rebuild kit for $50 a couple of years ago and just last week got around to doing the deed. I had to make a tool out of 3-1/2 inch, thick wall DOM tube and some quarter-inch stainless rod to remove the cylinder cap. Worked like a charm when I got my 250-pound lineman son to work the business end of a pipe wrench and cheater bar. The rest of the rebuild was easy-peasy and the 60-year-old, 1-1/2 ton jack now works perfectly - no leaks, holds my SUV up 14 hours without budging. If you see an old jack for sale, don't be afraid to snatch it up and rebuild it. Like Jnaki said, irreplaceable. But always, always, ALWAYS use adequate jack stands.
That's a good jack. Ours is well over 30 years old and works like new.. I do flush it out every couple years and when its cold I jack it up slowly a couple times with no load to get everything warm.. I keep it by the heater. My buddy always had all kinds of trouble with his. He used to keep it right next to the garage door which was almost as cold as the outside. He would grab it first thing and start lifting trucks up. I made a mental note of this and kept mine warm and pumped it up a few times before putting it to work... I'm not sure if it even has anything to do with mine lasting so long but I'll keep doing it..
