In 1981 in The Russians Are Coming (13th October 1981),Grandad Trotter had an old allotment that he had not used for 19 years since 1962. Derek "Del Boy" Trotter and Rodney Trotter were planning a dummy run in case there was ever a 4 minute warning of Russian missiles attacking Britain and Rodney suggested doing a one so they got their stop watch. In a couple of minutes they managed to get into the van but as they were driving through the back streets, they were stopped by Eric The Policeman. Eric was a friend of Del's and let him off. When Del asks Rodney how they are doing for time Rodney says "we died 45 seconds ago". The allotment was never seen.
11 years later, in late 1992, Grandad had been dead for almost 8 years and Del Boy found out that his paperwork had come thorugh on his flat and that the allotment came with the flat. Del also received a court summons to clear up the allotment as people were dumping toxic waste which could be an environmental hazard. That day, Del, Rodney and Albert went to the allotment to dump some of their old junk in the shed. By chance they saw their friend Trigger there. They found several drums of toxic waste there and contacted Denzel Tulser to help them dump it.
