| Auction house officials describe the phone as a "weapon of mass destruction" |
A telephone used by Adolf Hitler during World War Two is to be auctioned in the US this weekend.
It hopes that the phone, which is being sold by Sir Ralph's son, can fetch as much as $300,000.
Auction house official Bill Panagopulos said the phone was a "weapon of mass destruction", as it was used by Hitler to give orders that took many lives during the war, the Associated Press reports.
