Quick follow-up to my own post, the actual code I'm working with is more like shown below, so I there should be a vtable in play. 
Same question - how get at the SubClass object if I have a pointer to a SuperClass object using the Python API?


class SuperClass 
{
    public:
    virtual int fred() { return 1; }
    SuperClass() {}
    virtual ~SuperClass() {}
};

class SubClass : public SuperClass 
{
    public:
    virtual int fred() { return 2 ;}
    SubClass() {}
    virtual ~SubClass() {}
};

int main()
{
    SuperClass* pTest = new SubClass;

    delete pTest;
}
