A winch at Walka Works as previously shown.
Herringbone gear, of double helical design is seen there.

The logo of the French car, Citroen, is a graphic representation of a herringbone gear.
 Andre Citroen had early involvement in the manufacture and use of the gears in industry and in various early Citroen vehicles. Over time, the logo design has become more abstract.
Innovative far-out features like no other were/are usually offered to the motorist by this manufacturer. 

 Near Maitland, the old steam powered winch of 1910 was used in the construction Chichester Dam which holds the major supply of water hereabouts.
