A beautiful example of this 1950's design classic, with original case. The Bencini Koroll 24S uses ordinary 120 film, but exposes 24 pictures on it. The format is 3×4.5 cm. Just one shutter speed ( 1/50 sec and B ) and two apertures ( f:9 and f:11 ).
Minor split on the case where the plastic joins the leather, but otherwise stunning. Not tested with film.
