Figure 30a: Detail of current photo
Figure 30b: pre-restoration photo, scaled and aligned. In both, Z5 lies outside the image (only the very corner of the wooden cover and its shadow are visible in 30a). Images do not correspond exactly because they were not taken from exactly the same point (see Figure 33 and relevant discussion). The roof appears higher today due to added waterproof coating.
