Viewers are to get a glimpse of a 'lost' episode of Only Fools and Horses for the very first time.
The never-before-seen episode filmed in 1984, titled 'Licensed to Drill', is said to have been lying on a dusty shelf for years.
It features Del Boy, Rodney and Grandad at the top of their game, and is especially significant as it was Lennard Pearce's final appearance as Grandad before his death.
In the episode, Del Boy, played by David Jason, thinks he's on to a winner when he reveals his new get-rich-quick scheme.

And in another Nicholas Lyndhurst mispronounces his onscreen wife's name as "Ker-sai" rather than Cassie.
Gwyneth Strong, who played Cassandra 'Cassie' Trotter, said: "The outtakes brought back loads of memories for us, memories that you don't even realise are there until you start seeing that material.
"I kept saying 'Who knew!' all the way through watching it."
Steve North, General Manager for Gold said: "I am so excited to be working with the Sullivan family to help celebrate Gold's 25th birthday this year, and re
