A Fine And Rare Strasser & Rohde Glashutte Arithmometer, Similar to the T. de Colmar pattern, German, circa 1880, Div/Mul Sub/Add switch lever, 12 column carriage with individual window reset, flanked by cancel controls and seven further carriage windows, six input from 0 to 9, with calculation format change-over switch and black-slated door compartment, operation handle to right, main chassis of nitro-crystalline coated brass, interior mechanism of finely tempered steel and lacquered brass, within typical plain polished mahogany case with removeable hinged lid, makers plaque inside and swing handle to front, in working order. 19in. (48.5cm) wide
Footnote: Not many de Colmar-pattern Arithmometers turn up especially in this country. The interior mechanism design is very similar to that of the work and eventual realisation of Babbage's Difference Engine, with one size-convenient difference here being the manual lift-and-shift design of the readout windows for the input column turnover. This maintains complete control over which of the column readouts completes to carryover for both larger and smaller calculus.
Sold for £1,800
Estimated at £1,000 - £1,500
Appears to be in working order, has general wear consistent with considerable use, case has significant superficial wear, slate has full depth crack on one corner (in two pieces)
