BSI (Business Systems Incorporated (International) of the Netherlands) “Invader” golf ball typewriter elements were available in 9 type styles …
It’s interesting (if not laughable) to note that these print elements were advertised with a “forever” guarantee, yet the typewriters themselves were only guaranteed for 120 days.
Also of interest (in the advertisement above) is a reference to the Xerox 585. Who knew Xerox sold a very Sperry-Remington-like Selectric clone through their retail stores? Not me (in fact they sold two: the 585 and the 590).
The “Invader” advertisement also mentions “DSG” …

IBM really were under attack!

Interesting. I do not recall seeing anything BSI. I do recall the Xerox typewriters though.
Ha! Love that photoshoppery (:
Odd thing about BSI elements, most of the IBM gurus I know seem to avoid them, but I’m unsure if it’s the brand or just that they instinctively think they’re for another machine. That was always my first impression.
