Fully Jarvis oil leak

So, today while doing my usual cleaning routine I noticed an unusual darker spot around the desk’s leg/foot joint.

Upon closer inspection with better lights I realised that this is oil from the hydrolic (is this how it’s spelled?) motor in this leg.

So far the desk moves up and down but I’ve decided to not mess with it anymore until I have this figured out.

So I guess my question boils down to this: how f**ked am I? Where and how can I find a replacement system and how hard is it going to be to replace, especially since Fully doesn’t exist anymore? And how much is that going to cost me? I’m based in Europe, if it help in any way to know this..

Any pointers are greatly appreciated. Thanks!
