Art Deco silver Dunhill lighters with watches incorporated into the body are well known but this one, hallmarked for William F Wright, London 1926 has a barometer.
Auctioneers at Gardiner Houlgate of Corsham believe it is a one-off special commission.
Not even the German Lighter Museum, home of the world’s most comprehensive collection, has a similar model. It will be offered for sale as part of an auction of Clocks, Watches and related items on October 24, estimated at £1500-2500.
