Hundreds of items from an historic estate near Machynlleth are set to attract worldwide interest when they go up for auction this week.

Included in the sale of the contents of Fron-felen Hall, Corris, is a Prince of Wales Investiture Chair, which was one of 4,000 made in South Wales for the investiture of Prince Charles at Caernarfon Castle in 1969.

Made in vermillion-stained beech and plywood, it is embossed with the Prince of Wales motif in gold leaf and upholstered in Welsh tweed. The chairs are rarely found for sale, often kept by the same families since the royal ceremony, auctioneers say.

Other items from the hall 800-acre estate range from original paintings to antique furniture, including the investiture chair.

Built in 1826, Fron-felen Hall was once part of a large estate that included several slate mines.

Other items offered for sale include a 1920s Grandfather Clock, an Edwardian Mahogany dresser, a Chinese barrel seat, a William Strutt oil on canvas and gold sovereigns.

"This is an amazing collection of items amassed at Fron-felen Hall. It is like taking a step back in time. The Prince of Wales Investiture Chair is, perhaps, one of the more interesting items," said Tony Evans, a Partner at MMP/NL.

"The collection is wide and varied, from furniture to paintings and more modern items. We’re anticipating significant interest in most of the collection not only from the UK but from throughout the world."

The auction has been organised by auctioneers and estate agents Morris, Marshall and Poole with Norman Lloyd and Welshpool Livestock Sales.

The items are set to go under the hammer online at the-saleroom.com between Friday, June 11 and Thursday, June 17.
