ATD floor jack......

[Carpenter810]

Hello all! I know this topic has been discussed before as I have read the threads. However I still haven't found a definite answer. Photos are of my father's ATD floor jack. I know this is the brand because he owned an auto parts store and that's the brand he sold. I'm looking to rebuild it. It works fine and doesn't lose any pressure under load. However it's leaking in the rear of the jack around what I'm assuming is the cup? I can't find any stamping or model numbers anywhere on the unit itself. Believe it or not it was submerged in a flood in 97 and still works. Any info on where to look or how to start this project would be greatly appreciated.

Mine is similar and I‘m also trying to identify so I can rebuild. It might be a Viking (looks like maybe Viking made some jacks for ATD).
