Description
Used as a quick change option to keep the specimen centered and the fixed stage functional, Swift incorporated centering mounts for the objectives. This ensures that when the polarizer/analyzer is rotated, the sample stays at the center of the field of view.
Mahogany case is marked British made and patented by Swift and measures 15 x 10 x 5 cm. (6 x 4 x 2 inches).
The objectives (of various age) are 2 inch, 1 inch, 2/3 inch, 1/2 inch, 1/6 inch and 1/8 Oil Immersion in two parts. Excellent condition. Rarely used. The objectives require a specialized nosepiece adapter often with a spring loaded bayonet quick changer. All signed Swift and Son. Boxed with two wrenches.
Can be used for any model of Swift petrographic/petrological microscope from c. 1900-1950.
