The potential of a LC+DESY HERAp based gammap collider to probe the WW gamm
a vertex is presented through a discussion of the sensitivity to anomalous
couplings and p(T) distribution of the final quark. The limits obtained for
Delta kappa are comparable to the one which is expected from CERN LHC. The
bounds on the anomalous couplings are also found from a corresponding ep c
ollider using the Weizsacker-Williams approximation to compare with real ph
otons.
