Five Gestetnered pages containing the full original story breakdown for Episode One of the Doctor Who story 'Lungbarrow' and dated 20th June 1988.

Written by Marc Platt, the story got as far as having three full scripts commissioned and written before it was decided not to include it in Season 26 of the original series. Marc Platt was then re-commissioned to write a replacement story which eventually became 'Ghost Light' and was the last story to be made in the original run.

Gestetners were a fast and economical way to produce multiple copies of documents and scripts for distribution to the various departments of the BBC involved in production. They were made from the original document and these include some hand-written annotations by Marc Platt himself.
