French Miniature Furnace Microscope – c1850-60

Short Description

Scarce miniature Mineral or Furnace Microscope attributed to Bertrand, Paris in the Billings Collection pages 37 and 193. The Billings example no 369 on page 193 is identical even down to the circle made on the outer case from running the closing catch around.

Beautifully made, the original mahogany box has a conical dove tail slide cut into its top into which the instrument sits. The brass base screws to the tune stand. There is a square cut in the front that houses a single mirror on a milled head pivot. The stand is cut away for the fixed circular stage. At the top of the stand there is a screw in cylinder into which the body tube slides. There is an outer casing which slides downward to become a slide holder. The objective and ocular screw in.

This is a collector’s item – it is probably one of the smallest practical microscopes ever made, is extremely well made and in as perfect a condition one could expect for its age. The case is undamaged with a great patina.

Case dimensions approximately 85mm x 45mm x 35mm. Microscope height 75mm base diameter 25mm.

Perfect collectable miniature microscope – over 150 years old.
