ANTIQUE WALKER'S CHERUB MARK III SHIP LOG
SOLID BRASS PIECE OF MARITIME HISTORY
Great display item for the nautical collector!
The log is a recorder for determining distance traveled and thus ship’s speed.
It is made of brass with a ceramic dial, with the main scale marked from 0 to 100 miles and two inset dials marked from 0 to 1000 miles and 0 to 1 mile.
It has a fixing plate, on which it could turn, with which it would have been attached to a suitable part of the ship, typically the taffrail, the rail at the stern of a ship.
As a result, this type of log was often called a taffrail log. The recorder would have been connected to a rotor that was towed behind the ship.
The revolutions of the rotor registered on the indicator, thus measuring the distance traveled.
For this model, 900 revolutions of the rotor registered as 1 nautical mile.
Thomas Ferdinand Walker (1837–1921) first patented the Cherub log in 1878.

The Walker's Cherub III ship's log was manufactured by Theo Walker and sons in Birmingham England.
According to internet sources, it was likely manufactured during the 1930's.
The enamel dial is in a good condition with no cracks.
It has the original glass cover and the rear shaft still turns. It is likely, however, that the internal mechanism no longer works or would require repair.
The log measures about 24cm long and the dial cover has a diameter of 11.4cm. Weight is just over 3kg.
Please have a look at the images to verify age and condition and please ask any questions you may have.
