Being a HQ it will have 5mm thick spokes. The horn cap will have the Sandman badge but be warned these are being repro'd and being passed off as original.
If this one is the one off the Ute and the condition is excellent you should secure it. But it's value is around $400 to $800 and it would have to be very good and original.
Make sure the ring itself isn't broken and that the wheel sits flat on the rim on a flat table etc.
