There was no edger assembly ever released for the
Victa 18 Special. When the Model 5 was released
in the alloy base, the problems with the edger
had not been solved. Main prob being that of safety.
Therefor the new chasis had the concave edger slot
covered over with a plastic plate.
Later the edger slot was eliminated from the chasis base,
and this was the series 3 Special in green, and Series 4
in red for export.
