A partial set of British wartime Prime Minister Winston Churchill's gold-mounted false teeth, specially designed to disguise Churchill's lisp, were sold by the son of the technician who was commissioned to make them.

They had been expected to make a maximum of 5,000 pounds (about $7,600) at a sale by Keys auctioneer, but ended up netting nearly 15,000 pounds ($24,000).

"The atmosphere was electric," said a Keys' spokesman.

The buyer, a collector of Churchill memorabilia from Gloucestershire, also owns the microphone with which Churchill announced the end of the war in Europe in 1945.
