A mid-20th century compound monocular microscope kit, distributed by PBL, finished in black enamel with chrome-plated metal components. The instrument features a triple-nosepiece turret housing three objective lenses and a rack-and-pinion coarse focus adjustment with dual knurled knobs. It is mounted upon a heavy, U-shaped black-enameled foot. The main tube bears a printed white maker’s mark consisting of a diamond-shaped logo containing the characters P.B.L. followed by the text 40X-900X. The set is accompanied by a detachable mechanical stage attachment featuring two linear scales with millimeter graduations and vernier markings, adjusted by two knurled knobs. The microscope is housed in its original mahogany-toned wooden storage case with brass hinges, featuring a fitted interior including a dedicated rack for additional optics. The kit includes two interchangeable eyepieces, one marked 15X and another marked H10X.
