The theory developed in Part I of this series is applied to the general case of
a system consisting of colourfree quark triplets, whose quantum numbers are
chosen as collective trifermion indices. The appropiate mapping technique to be
used here is the baryon mapping. It is demonstrated that the original
multiquark states can be exactly represented by states of colourfree ideal
baryons. Besides, collective extended images are derived for a class of 
fermionic operators leaving the collective fermion space invariant.
