This example is unmarked according to the seller. The manufacturer, Vario-Focus model name, licensing and distributor have not been independently verified. It is therefore offered as an unmarked pocket microscope, not as a guaranteed branded instrument.\n\nEstimated date according to the seller: circa 1930–1950, spanning the interwar years and the early post-war period. This dating has not been independently verified. The seller describes the internal components as brass and the black finish as wrinkle paint; the exact materials have not been independently established.\n\nCONDITION AND OPERATION\n\nTested by the seller, who reports clear lenses. Operation and the stated magnifications have not been independently verified. The photographs show signs of use on the body, metal parts and case. Please examine all six photographs for the visible condition and included components.\n\nTracked shipping is charged separately.\n","brand":"continentalvintage.com","offers":[{"title":"Default Title","offer_id":59048484569352,"sku":null,"price":195.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1056\/0336\/7176\/files\/9783_7b4f21ae-47ba-4dd1-a3e2-6c5daed89dae.jpg?v=1791538584","url":"https:\/\/continentalvintage.com\/products\/vintage-uitschuifbare-zakmicroscoop-40-60-met-etui","provider":"continentalvintage.com","version":"1.0","type":"link"}
