with original case, but with broken glass tube. The military and other survey groups in need of forecasting weather in the field required a barometer that would not break when moved about. Among makers, Timby and Simmons probably sold more than others. The rear instruction label is intact, and we quote the most important sentence: "To render the instrument portable, gently incline it to an angle of about 45 deg., when the mercury will completely fill the tube, then turn the thumb screw directly across the instrument; it may then be carried with safety". It is uncommon to find the original carry case intact (leather handle has broken, but pieces are inside to use as a pattern). Also the black paper scale has some damage, but can be restored. The mahogany case front has been refinished; rear retains original finish and label. Thermometer is intact. Height of barometer 38", in case 39 inches
