CASED Antique c.1860’s brass MICROSCOPE and accessories by HARTNACK PRAZMOWSKI PARIS

Description:

A well-preserved instrument of excellent quality, this early Continental style microscope is signed on the draw tube, "E. Hartnack & A. Prazmowzki, Rue Bonaparte 1, Paris". A serial number of 14939 is stamped onto the inside edge of the fitted case and lens box, probably dates the instrument to the mid to late 1860’s.

This German brass microscope is equipped with an assortment of accessories and an elegant wooden case. A leaded brass horseshoe-shaped foot supports the microscope, which is mounted on a brass pillar that holds the mirror, stage, condenser, and body tube.

The microscope is finished in lacquered brass. A plano-concave mirror is mounted on a pivoted arm beneath the condenser. Focus is achieved by a rackwork set for coarse focus that translates the body tube up and down with respect to the stage and micrometer knob for fine focus. The eyepieces are of a Huygenian-style containing two lenses, and the interchangeable objectives are screwed into the nosepiece at the other end of the body tube. A slide out sub stage plate and further accessories are stored in lidded box. The microscope case, which is lined with purple velvet, contains a wide spectrum of optical pieces, including spare eyepieces and other assorted parts (please see images provided).

A small, green leather covered case contains three objectives and three diaphragm stops. The lens case is stamped with the same serial number as the larger case. Three eyepieces, marked as 2, 3, and 4 complete the optical system. The entire optical system works well, producing crisp, sharp images of good contrast throughout the extensive range of magnifications.

It even retains the leather padding that covers the bottom of the base.


Dimensions:

Assembled Microscope Height: 13 inches (33 cm)

The horseshoe base: 4 ½ inches (11.5 cm) long by 3 inches (7.5 cm) wide.

The original wooden case: 11 inches (28 cm) x 6 inches (15 cm) x 4 inches (10 cm)

Weight: approximately 4 kg


Condition:

In excellent antique condition. Cosmetically the microscope is very good retaining most of its original golden lacquer. Mechanically the microscope operated well. Optically the microscope is good with all lenses clean and undamaged.The case is generally in good condition, with some age related cracking across the top and back, strong hinges, overall stable and strong. The fitted velvet lining has some staining and a small tear approx. 2cm long. There is a lock, with the original key. It would be difficult to find a better example of this early Continental style microscope in such good condition.Please see the images provided which complement this description.


Shipping note:

The instrument will be double boxed, and dismantle before packing and shipping to reduce the likelihood of damage during transit.
