By all accounts these were two wonderful early British Television movies that have been lost in time , I had noticed several posts a few years ago mentioning a couple of episodes of The Trollenberg Terror had survived but to date never found them.



If these as complete shows are gone forever my question is did anything survive of them ie; photos or audio?



The reason I ask is that I have seen all of the lost Doctor Who episodes restored as recons using surviving audio and teli snaps and was wondering if possibly something on the same order can be done for these if photos or audio are available..
