Rear O/S Sliding Door Handle Disassembly

[Niknak]

Good evening, 

Just looking for instruction on Door Handle Disassembly...
I took my wheels to a mechanic nearby that i've used because he's nice and cheap to get MOT work done for re-test tomorrow. 
It had failed on a few things (nervous dog ate some seatbelts) plus the rear sliding door was not opening from the outside, but would from the inside.

 Anyway for one reason or another, he had failed to see to the door till earlier today, I think he was convinced a rod had come off, but it wasn't and he said the handle was broken and has sent me a link for one off the 'Bay.
And as I'm now going to mis my re-test (though I think I'm still going to go to get the other bits, seatbelts/wishbone bush/headlamp etc signed off anyway), I'm gonna do the door handle myself.

I've read all relatable threads on the forum here, but most of the photos are not available any more or its relating to a newer model, thus different. YouTube does not have any about the handle specifically, just door removal and rear/back van door locks...
Can anyone point me in the direction of ant helpful resources.. one that I can see the workings properly? 

Ideally a photo/vid or a schematic in Haynes style would be amazing.

The panel is off and when I got back, I could just see in the failing light how the inside door opening "button' works when you push it, and how the outer handle should interact with that mechanism. So it does looks like all the rods are attached.
I'll have another look in the morning when its light.

After reading the previous threads I took note about the Pin, and saw how common this is, so I have messaged the mechanic to double check and confirm that he actually did see the broken part of the handle and thats it not just the pin, before I order the handle...to br fair, the handle was replaced by the previous owners and it was super cheap, so could be that thats broken.

Hoping you can help  thanks... Niknak
