The firm's mark was a cockerel, and its Jacot tool was sold as the Hahn, the German word for the bird. The Hahn is still made in Switzerland today; this is an earlier example from the Steiner years, before Horia took the company over in 1992.\u003c\/p\u003e\u003cp\u003eThe frame is brass, 85mm along the base, with two uprights each holding a steel runner locked by a knurled screw at the top. The front of the left upright is stamped C and S in an oval, either side of a small cockerel. Four runners come with the set, each with a split collet end closed by a hex nut and a star-shaped brass collar for grip. Three are graduated runners, marked in hundredths of a millimetre and covering pivots from 0.04 to 0.30mm, from balance staffs up through the train; the fourth, unmarked, is the counter-centre.\u003c\/p\u003e\u003cp\u003eOn the left upright is the cable drive: a small pulley on a threaded arbor with a return spring along the bed, the drive Steiner offered in place of the fiddle bow. A spare spring is wrapped in paper. Three rounding discs sit in a two-part card tube, and the flat steel pivot gauge has its own place in the insert.\u003c\/p\u003e\u003cp\u003eThe case is black leatherette, 27.5 by 14cm, the lid gilt with the cockerel, the firm's turns-and-S emblem and the word for precision in German, French and Italian. The red felt insert is cut to fit each part.\u003c\/p\u003e\u003cp\u003eEverything works: the runners slide and lock, the collets close, the pulley turns freely and the spring holds its tension. The brass has an even patina with a few small spots by the right upright; the runners are bright. Light wear to the case at the corners.\u003c\/p\u003e","brand":"Steiner","offers":[{"title":"Default Title","offer_id":55275440570707,"sku":"CI-0053","price":595.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1080\/3121\/3907\/files\/steiner-hahn-jacot-tool-c1960-4_5a96b8cc-32c7-456e-924d-2bc4b0de7010.jpg?v=1791734529","url":"https:\/\/estatecollection.nl\/products\/steiner-hahn-jacot-tool-with-cable-drive-cased-c-1960s","provider":"The Estate Collection","version":"1.0","type":"link"}
