The Pradix was introduced in 1963 and was dropped in 1976.  An interesting
piece, as it had an aspherical condensor and, off the top of my head, I
cannot think of an earlier use by Leitz of aspherical optics.  It was
available with the standard 2.8/85 Elmaron lens (31403), a 2.8/100 Elmaron
(31400) (dropped in the later 1960's, probably as the 150W bulb couldn't
project brightly enough to allow full use of this lens) or with a 2.8/50
Elmar, replaced with an Elmaron in 1966 (31456).  The price for the 31403
was $81 in 1972, around $200 or a bit more today.
