VINTAGE engines from Britain's engineering past were still proudly puffing and chugging away as the final visitors left the Summer Fun Day at East Riddlesden Hall.
A Ruston Hornsby agricultural paraffin model from 1924 was the oldest on display in the bottom field of the historic National Trust property.
But Jim Pickles of the Aire Valley Vintage Machinery Club also pointed out the merits of the Armstrong Siddeley or the Lister CS Diesel which were also still going strong.
"There's been plenty of people today and there's been a lot of explaining just how things work," Mr Pickles said.
David Petty, chairman of the Craven Old Wheels historic car club was in his newly-restored Volkswagen W T25 Westfalia Joker mobile home, complete with rotating front seats and 1970s orange bodywork.
"I've been working on it for 18 months and only finished six weeks ago, so this is one of its first trips out," he said.
And parked beside him was Dennis Greenwood of Riddlesden with his classic 1952 MG YB dubbed "Charlotte II".
"This is our third time here. It's such a beautiful spot and there's something for everyone at the Fun Day - and it's free, which always helps," Mr Greenwood said.
Far enough from the children's bouncy castle and slide to pose no threat was the chance to try out the ancient art of archery.
Karen Hand, of Baildon, known as "the Handy Archer" was giving lessons for young and old with butts and targets placed within easy range.
"It has been very windy and if we were shooting at 100m as in the Olympics, obviously that would cause a problem.
"But we're only shooting at 10m and lots of people have come and had a go," she said.
National Trust volunteer for 15 years Judith Johnson spent the day helping out on the preservation charity's own stall and said the Fun Day had been well attended, but folk had fled after one late torrential shower of rain.
"It's been a very good day and hopefully given people a chance to come and see that East Riddlesden Hall is like a little oasis tucked away in a suburban setting.
"You just come off Bradford Road and the old house and its lovely gardens, plus the riverside walk are a complete and lovely surprise for anyone who comes," she said.
