the Cyberman and ther Dalek are "working" models - as is K-9.
hard to believe but the BBC actually "sold off" props from the show.
in the pix with DD is one of two real K-9 radio controlled models. about ten seconds after this pix DD was in the rafters when K-9's new "handler" lifted his head and moved forward.
John Leeson, K-9's "voice" - is in the background (blue jacket)
