  We apply techniques introduced by Clerc, Kobayashi, Orsted and Pevzner to
study the degenerate principal series of Sp(n,C). An explicit description of
the K-types is provided and Knapp-Stein normalised operators are realised a
symplectic Fourier transforms, and their K-spectrum explicitely computed.
Reducibility phenomena are analysed in terms of K-types and eigenvalues of
intertwining operators. We also construct a new model for these
representations, in which Knapp-Stein intertwiners take an algebraic form.
