Look kind of like BRM wheels. We don't get all the cool wheels on this side of the pond...

Magnesium Alloy Forging,Race quality and strength,
If you look closely you may discern what looks like push-out-pin marks on the face of the spokes,indeed that is what they are.The heavy pressures developed on the die made it necessary to remove the part from the anvil.Expensive process.
Worth every euro,rare.

Perhaps a series of photos of greater detail will determine the method used.Was any flash evident on the part?
After some searching,a number on the order of 500 sets were produced,as a source in Aus mentioned.
Removing the tire and testing for "ring-tone"when rapped is a sure method.
As similar designs were for certain pressure cast,perhaps that set was machined in a secondary op.
Pretty sure the test records are available to this day.

Edit:04/10/15
A longtime racer here has informed me that the wheels,though of very high quality,were pressure cast.500 wheels,not sets.

I like the look of those

Yeah they also sort of look like an older style of Ronals although they normally came in smaller diameters like 13". Popular on BMW 2002s. Cool look.

Not bad looking wheels. They look light!

These wheels are the Remotec diecast wheels of similar design.
Note the flash on the top of the ribs,aluminum alloy.
The magnesium wheel has thicker rib sections,and larger corner rads.

Nice looking wheels!
