A circa 1840 model of a paddle boat steam engine designed by Maudslay & Son is to cross the block at Bonhams.
It's expected to sell for around £15,000-20,000 ($23,450-31,266) as part of the Jonathon Minns Collection of Engineered and Other Models.
 Henry Maudslay designed the paddle boat engine in around 1840 |
Known as an oscillating engine, the design was used in Brunel's SS Great Western - the first steam powered ship to cross the Atlantic.
Bonhams explains: "Henry Maudslay (1771-1831) is generally recognised to have had the finest and most delicate design sense of any engineer of the early part of 19th century.
"Being commissioned from Rio de Janeiro to Istanbul he marked a new direction in the industrial world…
"Maudslay had these models built by the apprentices, for training, exhibiting and indeed, for recording the innovative development of the company's products.
"They were a popular type of marine engine and in general, 19th century models often followed this tradition and use. The highly polished appearance of this model illustrates the pride he took over his work."
Another lot in the September 22 London sale is a model Corliss horizontal jet condensing mill engine, which is valued at £10,000-15,000 ($15,633-23,450).
