  We discuss form factors and coupling constants for the $\gamma^* \pi^0
\gamma$, $\rho\pi\pi$ and $\gamma \pi \rho$ interactions generated by a model
field theory that produces finite size $\bar{q}q$ meson modes. The approach
implements dressing of the vertices and propagators consistent with dynamical
chiral symmetry breaking, gauge invariance, quark confinement and perturbative
QCD.
