Wellies on and kit off - that has been the (un)dress code for North Walsham Young Farmers' Club members during photo shoots for a charity calendar.

The lads and lasses have been stripping off in fields, barns and farmyards to capture the in-the-raw essence of each month.

Profits from the sale of their naked calendar will go to the East Anglian Air Ambulance which helped save the life of club member Jack Papworth's dad, Tim, six years ago this month.

Tim Papworth suffered a life-threatening brain injury after falling and hitting his head on concrete while trying to change a light bulb.

He was flown to Addenbrooke's Hospital by the air ambulance whose crew first stabilised him and placed him in a drug-induced coma.

The Papworth family farm in Felmingham was used as one of the calendar venues, together with Atthills Farm, East Ruston, owned by the family of club chairman Will de Feyter.

Ellie Marris, in charge of charity fundraising for the club, first had the idea for a naked calendar a couple of years ago but it took a while to convince county chiefs that it would be done tastefully and acceptably.

She said the North Walsham club's 43-strong membership had rallied behind the idea and had a lot of fun taking part.

'Hopefully it's going to be good for the charity and it's been good for the club - really relaxed and bringing us all closer together,' said Ellie, 21, from Bacton, a transport administrator with Veolia Environmental Services.

Everyone had pitched in with ideas for the photos which had included women draped across hay bales in a barn filled with 150 piglets.

A final photo with an East Anglian Air Ambulance is being arranged but Ellie stressed that club members would pose in clothes as they did not want to cause embarrassment to the charity or its most famous pilot, Prince William.

The calendar photographer was Westover surgery vet Elliott Simpson who had 'turned his head' while models unrobed and took up their positions, Ellie added.

The club is having 500 copies of the calendar printed. They will each cost £10 and will be on sale from the end of November from club members and through outlets including Ben Burgess, Aylsham; Ernest Doe, North Walsham; Papworth's butcher in Fakenham and North Walsham; Westover vets, North Walsham and Hainford; and the Lighthouse pub, Walcott.
