Floor Jack I.D. Help...

[1stGrumpy]

I am trying to id an old floor jack that I have, I bought it used many years ago but I don't know who built it. The only markings on it are on the base of the jack, there is an "8" and a "TR" stamped on it. Could it be TR Engineering? Here are a few pictures. Thanks in advance...

Looks like Hein Werner, not sure if I spelled that right. I will try to dig mine out and see for sure tomorrow.

Here's one that looks like yours

FINALLY finished my Hein-Werner restoration............whew!

Finally finished this beast! Took way longer than I anticipated but it came out pretty nice. Many thanks to Hiball for his rebuild kit and technical help and also to Elroy, without whose 2 rebuild threads, I wouldn't have even tried! Here's a couple of before and after pics. BEFORE...

I don't think it's a Hein Werner, at least not the ubiquitous "WS" - the give away is the pump style and the hex tank nut; those are more indicative of the typical asian import. Assuming you want to rebuild this, you can start here: https://www.garagejournal.com/forum/threads/overseas-jack-rebuild-help-tutorial.51105/

If you don't know the manufacturer, the best recourse is to take it apart and measure seals.

I believe that this is a Torin (Big Red) Model QKZ2. I have one from my grandfather that I am currently rebuilding. From what I know TR Engineering does not produce a floor jack however they offer a wide variety of hand pumps.
The grease zerk location can be telling as what specific model it is as well. Mine is off center which is how I got to this manual.
Were there any other parts attached that you can share?

It would help to see the rest of the jack.
