The 10 bells, a gift from the Ditchley Foundation of Britain, were rung for 45 minutes after a BBC radio broadcast transmitted to the ceremony the pealing of the Westminster Abbey bells, of which the Post Office bells are copies. The gift marked the rescue of the 84-year-old Romanesque Revival building and the 200th anniversary of the end of the Revolutionary War. The Ditchley bells were cast at London’s Whitechapel Bell Foundry, which also cast the Liberty Bell.
