Hey Rainer.Can,t find any interior shots of the later tiger.Just in a few Tiger pics you can see only one hole in the tigers turret mantlet instead of two.All I have found is this passage in "The modellers guide to the tiger Tank"by military minitures.Quote..."theT.Z.F.9b was a binocular gunners sight used for direct fire.Binocular sights were generally better for long term use,with less eye strain than the monocular sight."also read here for more info tiger tank development cheers .anyway the interior looks great so far.Keep up the spectacular work guys. :thumbs_up:
