Sale of a Large Achromatic Cooke


Sale of a Large Achromatic Cooke

The great refractor by Thomas Cooke and Sons oy York, which was shown at the International Exhibition of 1871 was sold by auction by Messrs Stevens of King Street, Covent Garden for about £750.

The instrument which had every modern appliance, and was one of the most complete ever turned out by the celebrated instrument makers was of 10 inches clear aperture and was originally priced at £1,200, but owing to the rise in wages and materials would now be charged much more. The purchaser was Mr Henley, the telegraph engineer.

William Thomas Henley was a submarine cable maker in Greenwich. He set up the Persian Gulf Cable which was 1,651 miles long. The success of which allowed him to gain many more contracts.
