Concealed close-coupled plastic toilet cistern - cannot find a replacement

Cool - the measurements will help.
I'd assumed they were all a pretty standard 1.5". 
A pic of the receiving end in the pan might help too.
The current control is a lever handle? I presume that is also an unusual design, with it having to protrude out forwards to get through whatever boxing-in there is? Will a new cistern suit this? Will the shaft come through in the same place?
Sounds like a 'mare job if you can't find the same size :-(

After having a closer look a SF I see 1.5" and 2", e.g. https://www.screwfix.com/p/fluidmaster-4550073-1-1-2-and-2-button-cable-dual-flush-bottom-inlet/58353 . It's 1.5, but can be used with a 2" hole - https://www.youtube.com/watch?v=cYDOR5Nvp50 . 

I wonder where the guy in the video got this transparent cistern... I want one!

'Low-level' cisterns (with a pipe) seem to have 2" valves as for the one I'm returning, the pipe fits into the outlet of the valve.

So, Ideally I need a cistern without a valve and to buy a valve separately.

I think you may have cracked it!
