this is frame 62 of Matt’s pictures of his MTB70 walkaround, this shows the view looking downward from inside the turret of the commanders seat with the turret rotation gearing behind his seat back, (not in view) on the floor bottom right, might be the stainless steel cover of the rotary base junction, showing that is the dead center of the turret floor. To the right of that is the edge of the drivers foot plate. the handbrake like control next to the commanders foot plate is the seat lever for raising the seat up and down.
