Schatz 1952 400 Day Clock – Unusual Styling Features

I recently repaired this Schatz standard 400 day clock dated 10 52 (October 1952). It has several unusual styling features:

The three finials are ball-shaped instead of spires,
The base cup is scalloped instead of smooth,
The 4 pendulum balls each have 4 ridges on top,
The back plate and front plate have a cutout on each edge (like Horolovar plate no. 1014B),
The arrangement of the back plate logos are different: The date is below the “No(0) Jewels Unadjusted” and the circle with 49 Jahresuhrenfabrik Germany is above,
The base has an extra vertical area at the bottom (usually the curve comes all the way to the bottom).
