no the split-prism was dropped at some point in favour of the much more advanced binocular periscope which gave a 3d image and depth perception. But the increased size of the mechanism meant dropping the split prism and aob finder and so relying on telemetry scales only.
it was considered an advantageous tradeoff
however, until our pc screens are similarly able to render in very high resolution 3d, to simulate this technological progress would be a step backwards, so we should stick with modelling the former.
