Westbury Design and Optical

Westbury Design and Optical were a visual effects firm ran by visual effects designer Clifford Culley who constructed seven new Dalek casings for use in Planet of the Daleks. These new casings were disliked by director David Maloney due to them being constructed from wood rather than fibreglass, and as such, these so-called “goon” Daleks were kept in the background throughout the story as much as possible.

The firm were also initially hired to construct the dinosaur models for Invasion of the Dinosaurs after the BBC Visual Effects Department determined that its resources were insufficient to build the dinosaurs required, but when the task of building the models proved to be beyond Culley's abilities, the work was ultimately subcontracted to Rodney Fuller.
