Head sculpt /paint application :
As previously mentioned, the figure comes with two different Head sculpt /paint applications. First up is the Grey plastic head mould with green paint application
Next up is the Green moulded plastic head with Grey paint application. Tan Limbs variants have this mould.
The green plastic can be seen quite clearly through the grey paint application that has rubbed away
I believe that the different types of head sculpt can be found on different COO figures.
