David Williams, from Bonhams' antique arms and armour department, said: 'There can be few pistols with a more interesting history than these magnificent survivors of centuries.
They are artistic and technological marvels of their time and remain today a window into the superb craftsmanship of the past. They were stolen by the Nazis from the Austrian string of the Rothschild family in 1938 and kept in a salt mine during the war to protect them.
The pistols were given to a museum after the war and were returned to the family in 1999. They're now being sold by a private collector who acquired them shortly after they were returned.
"The story behind them is fascinating but what makes them really valuable is their quality, workmanship and condition. They are incredibly high end pistols in fantastic condition."
