A broader flattened and padded safety hub was introduced with the 1959 W111 ‘fintail’ model. This engineering effort was years ahead of other makes. The padding may have been a false sense of security but the expanse would improve chances in case of accidental impact. Previous hubs were decorative and could be pointy (harpoon spear shaped).

Serving its purpose for years after having been liberated from Dad’s 1967 200 D (W110) which was pretty used up, I’m certain that this relic piece survived the car. It now lives on the shelf having been replaced with a reproduction part that is a near match to the original ivory one.
The wheel rim has stress cracks so it too will have to be restored at some point but Mercedes bling is like jewelry $$$. So, methodical pace.
These early cars had primitive seatbelts (if that) so any passive protection from the steering wheel is appreciated.
