the model KJ38 (Kadett-Junior, model
3300), which was a more traditional car
technically, but from outside it differed
only by the absence of a rear bumper. In

K38 differs from 11234 by: grill, bonnet ventilation sideholes, wheel disks (perforated on 11234 and without holes on
different position of traffic lights flags.
