The wheels in this photo are up to 1975/AM(Annee Modele)76, when they went to rectangular slots rather than oval.
The first of the GS Pallases shipped to Aus had the rectangular slotted rims (and the DS style more angular full wheel covers, rather than the ones on Kermit). The later shipments came with slotless rims that had a slightly indented pattern around the central area, still then used for a smaller cap on Clubs, etc.

(If I had a clue what was where here I'd attach a photo, but I don't and it's too late for me to be anything other than a "Space Cadet":) .)
