Objectives Ernst Leitz Wetzlar
I am looking for a case of objectives for an old geological polarising microscope Ernst Leitz Wetzlar 227915 (bought in 1925 in Stockholm). I lost my case by an unfortunate misunderstanding some years ago and I would like to buy one if I can find one. It had three objectives in it which were to be mounted by a type of clamp (the clamp is on the microscope).
Areometer (cylinder diameter: 4.4 cm) made of sheet iron and lead cone, both enamelled blue. In cylindrical can enamelled blue and gold (diameter: 7.5 cm, length: 29 cm).
French, unsigned, middle of 19th century.
This instrument was used for density measurements of minerals and gemstones.
