A microphone from John Lennon's home studio, in which he recorded early solo albums and hit song Imagine, has sold for £6,650 at auction.
The former Beatle had the equipment installed at his Georgian manor house estate at Tittenhurst Park, near Ascot, in 1970.
The house became the recording venue for the Plastic Ono Band and Imagine albums.
It sold on Friday night but other equipment is still up for auction.
Lennon was joined by his wife Yoko Ono, Ringo Starr and George Harrison in using the equipment during recording sessions.
Recording equipment specialist seller MJQ Ltd, which is handling the sale, is also selling a mixing console from London's Abbey Road studios, which has been used for recordings for the past 18 years.
An acetate disc used for mastering recordings, in which all four Beatles have etched their names, is expected to sell for tens of thousands of pounds.
A coffee percolator owned by Starr - who later acquired Lennon's home - also sold for about £400.
