Great and detailed work Ralph !
It seems his left hand should be resting on the rim
of a cuppola. Since he's free standing, perhaps
placing a scale 88 round underneath to
support his arm/hand.........?
As I stated, this one was done for a fellow collector and modeler. He builds 1/16th RC tanks and this figure was done for him to display in the turret of a Tiger.
