This is an extremely rare very early reichert with integral transmitted illumination. Serial number 12585. Finished in brass and black in very good condition. Twin objective turret with twin coarse focus and single fine focus controls and a focusing condenser. There is a field lens and filter carrier on top of the light box which has a ‘primitive’ transformer system and rheostat control. This still works although there no transformer is supplied because of current safety regulations. A superb collectors piece.
This is a relatively rare Cooke Troughton and Sims polarising microscope that is now a collectors piece. Serial number M702040 with provenance card and original manual together with its original case that is in excellent condition for its age. The body work is very good apart from the surface of the stage which shows the marks of slides as would be expected. Separate coarse and fine focus controls. Bertrand lens and a graduated rotating polarising filter. In/out analysing filter and mirror illumination.
This is a fine antique monocular brass microscope in its original case dating from approximately 1890. It has no makers name but there are features that attest to its quality. The cabinet itself is well made and which is very unusual for a microscope of this age it has its key. The brass is in good condition for its age. Large swivel mirror. Coarse focus controls with a separate fine focus system. The microscope has two objectives each with its own brass objective pot and ine eyepiece. The stage has a slide holder and very unusually has a dissection plate assembly with tether points that can be attached to the microscope stage. A genuine antique.

Leitz Drawing Attachment
Dating from the 1920’s this is a Leitz drawing attachment to fit monocular microscopes. It is rare to find these units that have all the accessory filters still in place. The mirror does show its age but without pickling or loss of mirroring. These drawing attachments depend upon a balance of lighting between the illuminated specimen down the microscope and the light available for the drawing paper hence the range of neutral density filters in the box which can be used to balance the two. Original case in good condition, a real collectors item.
