Help identifying floor jack

[nrj]

Hello all. Picked up my first long body floor jack and wondering if anybody can help in identifying it and its capacity. I'm guessing 4 ton but really don't know. A few dimensions for what they may be worth:
Length: 56"
Width front/back: 9"/6"
Wheel width front/back: 12.75"/17.5"
saddle height lowered: 4 1/2"
saddle height raised: 36"

No identifying marks/name plates that I've seen yet, except for Sweden on the base of the handle. Any ideas or direction to resources much appreciated.

After some more digging I'm thinking Nike is a possibility, and maybe it's more in the 2.2 ton range. The following link is all I've found re pics and specs of Nike jacks, and while newer the dimensions and design look similar. I don't know the weight, but two of us loaded it fairly easily so something along the lines of 150ish makes some sense. It didn't seem like the 200+ typical of 4 ton jacks.
