Code BA13052640: German Conpendium by LUFFT, c. 1900

This is a rare German compendium made by the famous instrument maker LUFFT.

LUFFT STUTTGART MANUFACTURER: Gotthilf Lufft (1848-1921) was in his younger years a technical assistant at the Polytechnikum in Stuttgart. He was responsible for the preparation of scientific experiments and maintenance of instruments and equipement. In 1873 he bought an optician shop in Stuttgart, w he started the manufacturing of aneroid barometers. Germany imported up to that date such barometers from France. The work shop became too small, after which he founded in 1881 the "Mech. Werkstatt G. Lufft" w aneroid barometers, compasses, hygrometers and other meteorological instruments w manufactured. In 1891 he moved his business to a new and bigger location in Stuttgart. Gotthilf Lufft was a real entrepreneur, always looking for new business. Together with the Nagel brothers he founded the "Contessa-Camera-Werke" which manufactured camaras. In 1926 they merged with C.P. Goerz and eight other camera producers to "ZEISS-IKON AG". On 23.05.1921 Gotthilf Lufft died. After WW I, the son of law of Gotthilf Lufft, Dr. Richard Möller-Lufft (1869-1944) was responsible for rebuilding the company. After having been active in France also by the acquisition of "Etablissements E. Hüe in Paris" up to 1939, all activities were concentrated in the pre-WW II period in Stuttgart. During WW II large numbers of aneroid barometers were produced. After WW II the company was rebuild again by Dipl. Ing. Erich Möller-Lufft. High quality and high quality were the key words for the products Lufft made. In 1986 the production of mechanical aneroid barometers was ended. Nowadays Lufft is one of the leading companies in the field of climatological measuring technologies.

This particular example contains three instruments: a compass, a barometer and a thermometer. I would place its manufacture date around 1900. It comes in a nice leather case that is still in excellent condition without any damage. The front lid contains the compass. The barometer is housed inside the case. Finally, the thermometer is housed inside the back of the case. Hinges are strong in their original condition.

The compass is very precise and points North without any problem. The thermometer is in working order and reads the correct temperature in Celsius and Fahrenheit. The barometer is also in excellent condition. It also comes with a rotating bezel for the use of the altimeter function. The bezel can be rotated by turning the crown. It is marked COMPENSATED, Serial Number: 12753, with the LUFFT logo. This particular example was manufactured for Rob. BRENNECKE, a jeweler based in INTERLAKEN, SWITZERLAND. The case is brass and in excellent condition without dings or dents. The barometer is in full working order and has been tested with an air bag. Measures 53mm in diameter.

This is a very unusual pocket combination set that would make a nice gift.
