The colour master tape of this episode was wiped by the BBC in the 1970s and the BBC only held a 16mm black and white telerecording. The episode remained only in black in white until the 1990s, when the colour signal from a domestic NTSC recording and the black and white telerecording were used to create a new colour master on D3 digital tape.
