      A class of supersymmetric preon models is considered in which the hypercolour groupGHC and the unbroken flavour groupGf anomalies are zero without needing spectators. It is shown that forGHC=SU(2) and SU(3) quarks and leptons as composites can be obtained satisfying ’t Hooft’s anomaly matching conditions. For the case ofGHC=SU(3),Gf can accommodate a horizontal symmetry group to describe just three generations.
