THE STORY
This is the second of three sci-fi adventures based on novels by Edgar Rice Burroughs, the first being 1975's The Land That Time Forgot and the third being The People That Time Forgot.

A Victorian scientist -- Dr. Abner Perry (Peter Cushing) -- and his young American backer -- David Innes (Doug McClure) -- set off in their new earth-boring machine for a short test on a Welsh mountain. Unfortunately the thing tunnels out of control at ferocious speed and they end up in an enormous cavern at the centre of the earth --  the twilight world of pellucidar. Here they find prehistoric monsters, man-eating plants and cavemen enslaved to the Meyhas (Mahars) --  evil psychic, pterodactyl-type creatures with extra-sensory abilities. They are captured, and taken to the Meyhas' underground empire. They then set out to free the slaves and themselves from the evil that has dominated this underground realm for untold generations.

 
Laurence Dunn noted that Frank had donated the Mole to the Model and Craft Museum, a private museum, where it was to be restored, as "Several of the grinding teeth were broken, the motor had rusted up, etc." 

Rod Jackson has lamented that the museum site "closed as an attraction in 2001 and I am afraid that I do not know what happened to the model after that." Rod checked with Frank's family and widow Doreen who did not know either. 

Laurence has called the museum to try to find out what happened to the iron mole. Alan Heaver, the original owner sold the museum in around 2001 and then it changed hands again in around 2011 and is now a military museum. All of the artifacts from the Model and Craft museum, including the Iron Mole (which the present owner does remember seeing but thought it was a rocket) were removed. They are still in touch with the last owner and have said they will make enquiries as to whether it still exists.
