Wright said the repairs meant the 91-year-old van could now attend summer events, including the Old Buckenham Air Show and, for the first time, the Royal Norfolk Show.
Speaking to BBC Radio Norfolk, he described the events as “some fantastic opportunities for those who have donated to come and see us and say hello”.
At the Royal Norfolk Show later this month, the van will be accompanied by museum volunteer and author Chris Garrod, who has published a new book called Jones’s Van: The Journey, to help raise museum funds.
It has charted the history of the vehicle – previously used as a baker’s van and a confectioner’s van – from when it was built in Dagenham, then part of Essex, in 1935.
It spent much of its working life in central London during World War Two before being found abandoned on a street in the 1960s.
BBC designer Paul Joel discovered it in a garage and adapted it for the sitcom.
It made its debut as the van of L/Cpl Jack Jones, played by Clive Dunn, who was a butcher when he wasn’t on duty with the Home Guard unit, in the third series in September 1969 – and made a further 18 appearances over the next 11 years.
The show, which at the height of its popularity was watched by more than 18 million viewers, was mostly filmed in Norfolk.
