right seeing as the range finder was never actually fitted to a king tiger before the end of the war the best i can find are model kits or Digital models/renders
Here is a link to a model, it appears accurate and also has the three piece engine access hatch

Here are two images of the Panther Ausf F schmalturm turret with a very similar rangefinder
And here is how the game War Thunder portrays the stereoscopic range finder bulges, as far as i can tell it is accurate although the war thunder model is a little old so it is not the highest quality (it was added when tanks were added to the game in i think 2014/15)
War thunder also portrays the engine access hatch in exactly the same way as the model, the central section of the hatch is symmetrical whilst the other two are mirrors of each other (the hidden one in the image is effectively identical to the visible just mirrored)
finally the IR night vision system, this one is the easiest as there is a 1/16 kit for it! here is the real thing fitted to the cupola of an Panther Ausf G
As far as i can tell the system was not fitted to the king tiger but it was certainly possible, here are two screenshots of the IR system and the schmalturm complete with range finder bulges on the sadly incorrectly modelled (wrong turret and gun) Panther II in war thunder, this should work fine on a king tiger however you may also need a new drivers periscope as the one on the panther could rotate unlike the king tigers
Again this is another old model so it is not the highest quality
Finally here is a link to a very nice but expensive kit for the cupola IR system, i am not sure if there is one for the driver though
