Product Description for Wetli & Starke Planimeter No. 44

This flyer is printed in German and describes the capabilities of 1986.0633.01, a wheel and disc planimeter invented in the mid-19th century. It was printed by Ludwig Mayer in Vienna and is marked: Draht Nro. 3 (11). It is signed by Starke & Kammerer. Gustav Starke (1832–1917), son of the Vienna instrument maker Georg Christoph Starke (1794–1865), formed a partnership with Karl Kammerer in 1873 that sold scientific instruments until 1917, although Starke apparently moved to Switzerland by 1904. Their sons, both named Gustav, operated a branch of the firm in San Francisco from 1889 to 1892.
The photograph also shows 1986.0633.03, an older copy of the flyer; three tacks and a key that were found in the case for 1986.0633.01; and a heavy spring around a bolt with a hook that was received with the object but apparently does not belong to it.
