Thanks to everyone I was able to positively identify the floor jack.
It is a Weaver WA-73B 4 ton floor jack. I was able to match up the frame length and front wheel diameter.
I am trying to find out anything and everything about this old floor jack. I can not find any identifying marks. The old name plate is unreadable.
I am wanting to rebuild the hydraulic cylinder and any information would be helpful. Name, Model, Capacity?
I do know that it is very heavy duty...
