Introduced in late 1982, the Super did not sell in large numbers. The instruction manuals suggest that the range ended production in late 1985. Serial numbers start in the range 25xxx with the collection range being 2507702 to 2506570.
The Supers had a bit of a quality problem with shutters sticking and a common problem is the centre cover of the film advance lever falling off! Neither of these issues were addressed by Pentax so working Spers are today very hard to find
