[1] Allnatt purchased Peter Paul Rubens' 1634 painting Adoration of the Magi for a record £275,000 in 1959 from the estate of the Duke of Westminster.
The painting was estimated to be worth $2,400,000 in 1974, when it was damaged by vandals who scratched "IRA" in 2-foot-high (0.61 m) letters across the front.
A horse named Ujiji owned by Allnatt finished third in the English Derby in June 1942 and first in the Gold Cup in 1943 at Newmarket, England.
[citation needed] Allnatt died at his residence Doughty House in Richmond Hill, Surrey and his ashes were buried in the churchyard at Turville, Buckinghamshire.
[citation needed] He and Melvin Leroy Merritt of Portland, Oregon, United States researched and published a genealogy book of the Allnatt history, The Families of Allnutt & Allnatt, in 1962.
