ONCE again, readers were quick to identify last week's mystery object.

It was, in fact, an antique pocket calculator, dating from between 1910 and 1914.

There were correct guesses from Anne Lindsay, Cath Cooney, Jonathan Mosley, James Monksfield, David Heather and John Fletcher.

And two readers, Valerie Mason and Brenda Wood, even managed to identify the manufacturer, William Henry Fowler.

Experts at Craven Museum and Gallery tell us: "The calculator is made from glass, metal and paper. It measures 70mm in diameter and the front scales are for multiplication (three scales), logs and sines. The rear scales are for finding cubes and cube roots.

"The crown drives the front dial and the button in the centre of the back drives the rear dial and the pointer over the front dial.

"This style of calculator was only made in the years from 1910 to 1914 and was presented in a maroon card case with instruction manual.

"Fowler’s were established in Manchester in 1898 and continued until 1988 when the company was liquidated. It made many other types of calculators."

All items featured in this column can be viewed at the museum, which is run by Craven District Council and is in Skipton Town Hall.

Meanwhile, we are inviting guesses about this week’s mystery object. Suggestions can be emailed to news@cravenherald.co.uk, to arrive no later than noon on Monday.
