Last week

Sunday Tasmanian - Tassie Living - - HOME -

AC­CORD­ING to the Archive An­tiques store owner, last week’s mys­tery item is an Ot­tis King slide rule used for mul­ti­pli­ca­tion and divi­sion. It was made in Eng­land and was pop­u­lar in the days be­fore dig­i­tal cal­cu­la­tors.

Three dozen read­ers wrote in with that same an­swer, which was a great turnout for week one. The fastest of them were: Max­ine Burger, Tony Hor­sham, Stu­art Hadrill, Charles Spiegel, Michelle Cooke, Robin Gil­mour, Stephen Pen­neyston, Cedric Lock­ley and Brian Young. Arthur Sale PhD wrote to say it ac­tu­ally was not a spi­ral slide rule but rather a he­li­cal slide rule.
