The KW made Praktina had a direct view finder which was later copied by Pentax with the Asahiflex 1 (their first SLR) I'd guess this is being muddled with a rangefinder.

It would be interesting to list what cameras etc were released around 1958 because that's the watershed when Pentax brought out the first of their modern Asahi Pentax SLR's with semi-auto aperture control, instant return mirror, better Pentaprism and shutter speeds, that's mirrored by other Japanese manufacturers like Minolta with the SR-2, Nikon joining them a year later.
So the OP's right to highlight 1958 as a key fime of change.
