Where under a bequest (whether specific or general) a person is entitled, beneficially or otherwise, to—
(a) the manuscript or other support on which a literary, dramatic, musical or artistic work was first expressed in material form; or
(b) the material support embodying a sound recording or film,
and the work had not been published before the death of the testator, the bequest shall, unless a contrary intention is indicated in the testator's will or a codicil to it, be construed as including the copyright in the work in so far as the testator was the owner of the copyright immediately before his or her death.
