First broadcast on the BBC on July 31 1968, Norfolk and Suffolk have a proud connection to the series - written by Jimmy Perry and David Croft - with most of the external scenes having been filmed in the area.

Attracting 18m viewers, the show was one of the most watched television programmes of the time. It gave birth to a host of catchphrases - including, “don’t panic”, “stupid boy,” and “we’re all doomed,”.

“The catch phrases have become ingrained in our psyche and I think they will be for many more years to come.”

He added that people from across the world visit the museum, which held a celebratory event on Saturday, such is the show’s everlasting popularity.

“Thetford continues to benefit from tourists who come in and we had our busiest ever year for tours,” he said. “The museum’s biggest complaint on Trip Advisor is why aren’t we open more.”

Bressingham Steam Museum and Gardens, near Diss, also sees a lot of visitors and has been the official home to the Dads Army Appreciation Society’s collection since 2000, and includes a recreation of Walmingtonon-Sea.

Dad’s Army and Thetford

Locations in Thetford used to film the series include the Guildhall, the former Place Cinema and the flint cottages of Nether Row.

Many extras for the series were drawn from the Thetford Music and Drama Society or the Thetford Senior Citizens’ Club.

In 2010, a full-size bronze statue of Captain Mainwaring was unveiled in the town by series writer David Croft.

The Dad’s Army Museum was founded in 2007 and is housed in the Old Fire Station. It contains exhibitions and photos featuring the show’s most famous stars as well as a display on some of the stars who made brief appearances, such as Barbara Windsor.

Jones’ van from the show is housed at the nearby Charles Burrell Museum.

The museum also has the 1940s-style Marigold Tea Rooms, with war-time recipe cakes.
