recently sculpted these i found the art work for the skulls a long time ago i think its steve dillon but im not 100%. but just got round to doing this hopefully have gunner and helm to attach them to shortly.
i had the chips machined out of styrean then sculpted the 3 skulls seperatly in wax then moulded those once i had cleand up the resin skulls i attached them to the chips and then moulded those as a compleat unit.
