About this detail of the Tiger
The floor of the Tiger tank was made up of removable panels. Most of them were at the level of the turret floor, but behind the driver there was a large panel at a lower level. This panel is shown below.
This is a single piece of floor panelling, flat towards the rear of the vehicle but slanted downwards at the front. The underside of the panelling is strengthened by metal bars, of L-shaped cross section.
Flush in the middle of this panelling there is a hatch (drawn in red) which can be lifted out via 4 finger holes. This hatch covers a tool stowage bin. Behind the hatch is an oval holder, made of sheet metal strips, for an oil can (the kind with a spout). To the right of the hatch, a long rectangular hole is cut in the floor, for some lever or other.
Also to the right of the hatch is one of the headset stowage boxes. There are two identical ones in the rear of the Tiger's turret, marked "1 Fernhörer 1 Mikrofon", but this one is unlabelled.
This assembly was bolted to support frames in the vehicle's hull, almost touching the hull side. The driver's seat, when folded right back, would have rested on it.
This drawing shows the panel as it was at the beginning of the Tiger's production run. By the end of the series, the headset box had been moved from the floor up to the radio equipment rack.
