Trying to ID this Jack to repair…

[Keyblazer]

Hey,
Anyone ID this Jack I got?
I think it’s a trans Jack but it’s big, and heavy.
Doesn’t look or feel like an import.
It looks like it was orange originally, but was painted the blue you see.
The is a sticker on it that’s yellow but after rubbing off the blue paint with MEK, I can’t see ant writing.
It doesn’t pump up….even tho the oil is full.
If I can ID it, maybe I can find the seals.
Any help would be much appreciated!

Wow, that's an interesting one. No idea what it is

Thanks for the input.
Yeah, I’ve searched and searched.
It looks similar to a Snap-On 1/2t unit but different enough, and looks bigger too.
The oil reservoir is full, but it won’t pump up.
