The historic, steam-driven engine returned to the Oxfordshire estate following a years-long search.
The event was organised by Woodstock Fire Station’s Watch Manager Nick Mason, who also helped return the vintage engine to the Palace earlier this year.
In 2018 Blenheim Palace’s Operations Director, Heather Carter, launched a nationwide search to track the engine down and return it to the Palace.
The Victorian engine now has pride of place in the Palace’s new Stables exhibition, alongside two other manual fire engines dating back to the early 18th century.
“The Fire Cadets did an amazing job of getting the old engine looking like new and we’d all like to thank them for their hard work,” said Heather.
“Since its return it has proved to be one of the exhibition’s most popular exhibits and it’s great to think that, after all these years, it’s still being looked after by future local firefighters,” she added.
Believed to have been built by Merryweather & Sons in 1890, the horse-drawn engine used a steam boiler to create pressure to pump water. It was mounted on a four-wheeled sprung carriage.
After many years of operation, the engine was taken out of service and showcased at various Victorian steam shows around the country before settling at Shipston Fire Station then Nuneaton.
Blenheim Palace incorporated its own brigade in the mid to late 1800s and owned a variety of fire appliances, including the Merryweather. The brigade was still in operating during the Second World War.
