I’ve discovered a sixth element, to go with the five golf ball print elements I already own…

I’m not sure what the two numbers on the cap relate to.

Three holes on the cap allow the ball to be secured on a plastic base …

Before being encased …

The Olympia “i” logo on the base is clearly visible …

This element is relatively hard to find and was used in the Olympia SG 75 (1975).

As far as I know, this was Olympia’s only kugelkopf (golf ball) typewriter. According to the Kleines Schreibmaschinen Museum, 10, 000 SG 75 typewriters were manufactured.
