The mummified arm of a criminal hanged in the 19th Century has been handed to the National Funeral Museum.
The pair were executed in 1813
In 1812, George Ruddock and George Carpenter were sentenced to death for the murder of farmer William Webb, and his maidservant, Mary Gibbons.
The pair were publicly hanged on gallows erected near Warminster.
The bodies were removed to Salisbury and dissected but the mummified arm of Carpenter was retained by local surgeon, Dr Charles Kindersley.
He donated it to Wiltshire Police in 1938, who put it on display at the police museum in Marlborough, which has now closed.
Carpenter and Ruddock were hanged on 13 March 1813, after a procession to the place of execution that involved 2,000 "Peace Officers".
The National Funeral Museum, currently under development, will trace the changes in funeral traditions over recent centuries.
John Harris, from Cribbs Funeral Directors in London, said: "I am honoured to be taking on this very historical, unusual and somewhat gruesome reminder of what went on all those years ago on a dark winter's night in Wiltshire.
"It will be an interesting addition to the museum."
