A plane spotter is set to auction his two rare Concorde models.

The aviation enthusiast, who is from Worcestershire, waited 25 years to acquire the 8.9-foot replicas of the world’s first supersonic passenger airliner.

However, the plane spotter has decided to part with his cherished models due to health concerns.

The Concorde models are expected to fetch a combined total of £16,000 at Hansons Auctioneers on Thursday, October 24.

The seller, who has owned the models for more than two years, said: "I would have sold a kidney to get them.

"They're beautiful."

The models were initially commissioned by British Airways in the 1960s and 70s for promotional purposes.

They were displayed at Harrods in London during Concorde’s heyday in the 70s and 80s.

Steve Fulford, a valuer at the auction firm’s Derbyshire saleroom, said: "The models are fantastic collectors’ items.

"Only a handful were ever made.

"Our vendor managed to acquire two of them after waiting for 25 years.

"One of his models is thought to be unique.

"Of the other examples known to be in existence, one is in a Cornwall museum while the whereabouts of another five are unknown.”

The unique model of the British Airways Concorde, G-BOAC, features a cutaway section revealing the seating and cabin arrangement.

It is believed to be the only model of its type and size in existence and is expected to fetch between £7,000 and £8,000.

Mr Fulford said: "Interest in Concorde, a French-British collaboration celebrating engineering excellence, has intensified."

The seller's passion for aviation was kindled by his father, a fellow plane spotter.

He said: "Aviation has always been in my blood."

Despite his love for planes, the plane spotter never fulfilled his dream of flying on Concorde, but he did achieve his teenage ambition of owning the models.

Mr Fulford said: "Due to health reasons, our client has decided to part with much of his collection, including the Concorde models which he has owned for more than two years."

The seller's dream is for a museum to secure the Concordes to help future generations understand aviation history and the part Britain has played in creating world-beating aircraft.
