An Antiques Roadshow guest was left stunned to discover the huge value of a Louis Vuitton trunk which had spent decades in her parent's attic.

Sunday's show saw members of the public bring their treasured items to Thirlestane Castle in Scotland, with one lady keen to learn more about the designer accessory.

Expert Raj Bisram recognised the luxury brand immediately as the guest told him: ' I think [my father] used it to stand on while decorating and painting the ceiling'.

'Nobody thought it was of any value, then someone opened the chest and looked inside [at the label] and thought "that sounds really familiar"'.

After admitting she knew little about handbag manufacturer Louis Vuitton Raj explained: 'They actually started off making trunks, they started in 1884 in Paris'.

He revealed how the lock system that was invented at the time is still used by the company today and even outsmarted famed magician Harry Houdini. 

Raj went on to explain how the trunk was one of the brand's first as it was missing it's now infamous LV logo, which was created in 1896.

'In this condition, a chest like this, is definitely worth somewhere between £1,500 and £2,000'. 

Shocked the woman was lost for words and giggled before admitting: 'It has a lot of sentimental value and despite the valuation it means a lot'.

It comes after another show guest was lost for words when Expert Mark Smith met one man whose father was an SAS soldier as he showcased his paperwork, medals and badges - which are often 'faked all across the world'.

The man showed a black and white photograph of his father, called David Cargill, before being sent to France with the BEF. 

Impressed by the collection on the table, Mark said: 'You said to me this morning 'my dad was a soldier' then you started to get this stuff out and I got so excited because this man was in the SAS, this is fantastic.' 

'We have a Territorial medal here. He went to France and he starts off his war by coming off a beach, somewhere called Dunkirk because he has the Dunkirk medal as well. What did he join then?'

The guest replied: 'He joined the Parachute Regiment, did his training and once he'd got his wings, he immediately volunteered for SAS and was accepted.'

Mark continued: 'Now, when you see these badges and things that you have here and you see SAS wings, usually they are fake. You have a Kings Crown Parachute Regiment badge. 

'Even they today are hard to find and usually they are copied as well. You then have two of the shoulder titles for the 1st SAS. Now, I'm not certain that I've ever seen those before, in the flesh to actually touch them but there they are.'

Mark was particularly impressed at the beret that belonged to the guests father as it obtained genuine details, including the little badge that he said was often 'faked all across the world'. 

Mark added: 'These things just don't come on the market, so to actually be able to stand here and touch the real thing, it's fantastic!' 

Putting a value on the items, the BBC star said the medals alone were worth around £200, with the full collection worth close to £8,000.

The guest was stunned by the valuation and said to Mark: 'My father would be very surprised.'
