Talk:Episode 1135 (1st December 1971)

I noticed the staircase on the wrong side of the hallway in this episode. I see that you've noted this abberation on the page for Number 13 and referenced Episode 1069. Any idea how often this happened and if it was just during this period?

Also,I wonder if there is some damage to the master tape for this episode,as I noticed a few glitches(sorry,not sure of the technical terms)on the DVD edition of this episode?
