Nether Row (renamed Percy Street in the show): pops up frequently in Walmington street shots, including the corking but rarely repeated missing-knickers episode Man Hunt.

Thetford Guildhall (Walmington Town Hall): the Time on My Hands episode (or The German Pilot Trapped on the Clock Tower One to give it it's full title) is centred almost entirely on the 19th century clocktower..
You'll also find Mill Lane, perhaps Thetford's most viewed road seen during the closing moments of The Deadly Attachment (or The 'Don't tell him, Pike!'One to give it it's full title), The Bell Inn - lodgings for the cast during location work, also used for the opening shots of the debut episode. All these, the Dad's Army Museum and plenty more Walmington backdrops are all doable and viewable within a one hour wander..
We would have factored in a trip to the Bressingham Steam Museum if we'd known of the gold contained therein. But that's another trip for another time...

It's the rare version pop-pickers - see if you can spot the extra lyrics ?
