Can anyone identify this wheel?

[Lefty]

I bought four of these, 2nd hand to use for winter tyres. One of them was badly scuffed but looked worth refurbishing. unfortunately it's buckled beyong repair

They are OZ superturismo's but anyone know which superturismo? There seem to be a few sub-models, with slightly different centres. LM, WRC etc.

Any help much appreciated!

Cheers,
Lefty
