A 1974 bet on Red Rum to win the Grand National has been cashed in 43 years late, after a man discovered a betting slip among the belongings of his late father-in-law.
Bob Holmes contacted bookmaker William Hill after finding the betting slip, who confirmed that the punt had never been cashed.
The bookmaker paid out £130 on the bet, plus a £130 free bet on this weekend's Grand National and the same amount again to donate to the charity of Mr Holmes' choice.
It is thought to be a record-late cash-in, with William Hill adjusting the payout for inflation. The betting slip read: "1 win. Red Rum. Live 3.15."
Mr Holmes, a 76-year-old retiree, said: "My sister-in-law was moving house and my wife and I were helping her to see what could be thrown out, so I was looking through a whole pile of old papers, tax returns, bank statements and so on.
"I came across a scruffy bit of paper that turned out to be a betting slip that had been placed but never cashed. When I looked more closely it was for Red Rum in the 1974 Grand National.
"I contacted William Hill who said yes, it is a bet that has been properly placed and they would not only honour it but would increase the value to today’s prices.
"It is a mystery [why it was never cashed]. My father-in-law probably lost the betting slip and was not able to cash it.
"It was very rare for him to bet. He was not a betting man, maybe a couple of times a year on the National or the Derby."
Mr Holmes has said he is splitting the £130 free bet for this year's national three ways with his wife and sister-in-law, Rhoda Robertson, with each of them backing different horses.
Mr Holmes has plumped for Blaklion, his wife Nancy has gone for Definitely Red, while his sister-in-law has backed Ucello Conti.
Graham Sharpe, spokesman for William Hill, said: "It is certainly a record.
"I’ve worked at William Hill for 45 years and the record before was seven years – for a lady whose husband had passed away and she had not felt able to go through his clothes until then, and had found a betting slip."
“If you have a valid betting slip we will always honour it because we understand that things like that happen.”
