Hello wce, speedy and Norm
I believe the Victa Concorde was a store brand, rather
than part of the Victa range.

wce, would it be possible to get an image of the front decal -
on the dress cowl. I suspect this was a Betta Electrical job.

The issue of the 'curvy bladeholder' is worth consideration.
As Norm said, Rover (and others) stuck with a classic design, but with
four fluted blades.

Since the 1970s, Victa seem to have been on a mission to
reduce the number of component parts. We see this in chassis design,
engine design, carby design and ignition design.... everything!
Fewer parts - lower production costs - quicker assembly -
higher profits.

If you could get a curvy, pressed bladeholder to do the job of a
set of blades, then there would be an advantage. The other interest
Victa had was in reducing noise.

It is recognised that most mower noise is aerodynamic - from the
cutting action and the engine flywheel - not the exhaust.

Here, we understand Victa's collaboration with CSIRO on a new blade
holder that would be licensed for use on the Victa Vortex.

Cheers
