here are a set of four rare Cosmic Mk2 (or Cosmic RW) vintage alloy wheels, which was a popular period-correct aftermarket choice in the late 1960s and 1970s. Because the Rover P6 has a highly unusual 5x127mm (5x5") bolt pattern and a unique high positive offset to clear its de Dion rear suspension, custom-drilled 5-stud classic wheels like this are quite uncommon and highly sought after.
