Yep - 6 screws on the bottom. Picture below attached of the innards for your curiosity @CXRAndy - just a tiny pcb and a angle sensor basically.
Also yep - the bumps are just soft end stops at the extremities of the arc.

Thanks Pete.
I wonder if it is just a variable potentimeter. It could be optical or hall effect.
Did you see if a lever connected directly to the pcb or lever but doesn't actually touch the pcb?
Looking at the size of the pcb, it could be transplanted into a little box and a lever cobbled for the hand to adjust. I bet the pcb could be nibbled down to make it even smaller.
@bridgy It does seem alot of cash for what's inside. That's the way, demand will drive the price
