Fans have the opportunity to grab a piece of Duton history, with the third and final Duton Abe film, being a hit on the big screen in September.
Props, costumes and set pieces are being auctioned for donations during the series.
They include the vine wall from the servant hall, and the family car – a 1925 sunbeam.
The exhibition at Bonhems at New Bond Street will remain open until the closure of September 16.
