The pentagon shaped caps appeared on both the VH & VK model Commodores/Calais, also another version was on the JE Camira (not interchangable with Commodore). Anyway the logo on the VH cap had the lion with the line running underneath. The VK version did away with the line running under the lion (it kind of looked unfinished). This VK cap also continued on the VL as an optional alloy wheel on the Berlina's (not to be confused with the Calais polished alloy wheel with the round cap). I hope this helps.
