The second picture is of course a prototype BT-5IS.

All of that has been pretty well established already, I think. The 4mm bulkheads apparently were not made of armor grade steel, but softer structural steel (perhaps not quite 'mild' steel, but still).

The really interesting thing here is that it shows 20mm turret front armor just as Jaeger Platoon specs claimed. Perhaps I should write JTV and ask where he got them, but my guess is Baryatinskiy's "Light Tanks".
