Have there been any kinds of statements to this effect in articles or anything Id be hesitant to do so without an official statement as they couldve been simply reusing a clapboard from Chris Ecclestons time no Plus I dont know whether what it says on the clapboard should be treated as official  heck IIRC in some of Tennants video diaries there was at least an episode or two whose name changed between filming and air Gah I just realized  not to shoot you down but without an official statement from the BBC or reports in other RS like the media I dont think we can use visual evidence from the clapboard  I would argue that runs afoul of WPOR particularly WPSYNTH
