This small tilting microscope is only 19 cm tall. Its focus system is manual, rotating the optical tube. It has only one objective. Its square stage is fixed and has a curious fixing system for lyre-shaped preparations. It is a tiltable microscope by means of a curious system of a steel sphere that joins the apparatus to the stand. A screw in the base makes it possible to harden the tilt mechanism by acting on the base of the microscope. A similar device also from an unknown manufacturer can be found on page 67 of the BCC, nº125.
