Production of the first Leica I Anastigmat, the world's first successful mass produced 35mm camera subsequently commenced in late 1924. At the time this microscope was made in 1923 the first 31 "Null Series" Leica prototype cameras were being built and evaluated and the board was deciding whether or not to put the first mass produced Leica camera into production. The microscope is not particularly rare but the fact that the instrument is in remarkably excellent cosmetic and functional condition is testament to the superb quality of E.Leitz design and engineering. The condition suggests that Ernst Leitz used exceptional quality brass lacquer. Two additional keepers are not included in this photo.Ĭlose-up of the microscope body and part of the drawtube with the engraved S/N 210693. These are the filters for the sub-stage condenser on top of one of the chamois leather clothsįoot now swung open, sub-stage swung to horizontal, stage clips inserted, objective lenses screwed into lens turret, eyepiece inserted into drawtube.
The instrument S/N is also embossed on the corner of the caseĪll the objectives and eyepieces are present and correct as per the certificate but the 7x objective seems to have been replaced in 1929 as per the annotation in the cap of its brass keeper Above the certificate is the brass nameplate of the Swiss agent: INDUSTRIE GÉNÉRALE d'OPTIQUE Marcel WIEGANDT 10 Grand Qual GENÉVE. It is thus in remarkably good condition for an 85 year old document. The original Ernst Leitz certificate for instrument S/N 210693 dated 21 March 1923 is in the lid and protected by a piece of acetate. But the lens was not part of the original equipment according to the certificate. There is an empty E LEITZ WETZLAR brass keeper with engraved cap reading "1/12 Oel Immersion" so at some stage the oil immersion objective may have suffered from the type of oil used ie cement may have been penetrated the lens element and thus the lens was abandoned.
