Description

A quite rare model of a Jecker drum microscope in brass we can date around 1810.

The microscope is unsigned but this is exactly the work of François-Antoine Jecker : the model, shape and knurling are exactly similar to the other ones signed known examples.

For a comparison, see the recent Stevenson’s FB post, here :

 

The present model has only one difference with the others known : the two screw to move the sub-stage mirror. Here, the simple screw seems to have been modified to move easlier the mirror without having to put the hand in the drum base.

 

Jecker was selling four different forms of microscopes, all quite rare : a classic Culpeper-type of which we know some examples, a very rare Amici-type catadiodriptic microscope of which we know only two examples, and two different drum-type microscope of his own invention : a large form and a smallest form, this one.

 

The microscope measures around 160 mm height and it is in fine condition.

A rare and original form of a French drum microscope, circa 1800-1820.

The last one similar signed example was sold for 2000 euros hammers few days ago in France.
