Brief Description: The instrument is painted black. A housing standing on the horseshoe foot carries the stage, condenser, mirrors and curved limb. The housing holds the mechanism for fine focusing, adjusted by knobs on each side. The limb moves on a rack and pinion for coarse focusing. The Siedentopf type binocular head is set on a swivelling mount at the end of the limb. A rotating objective changer, with sockets for three objectives, is mounted below it. Eyepieces drop into tubes in the head, which pivots to set the inter-ocular distance and can be locked in place. The right hand eyepiece can be focused independently. The stage is mechanical, moved by rack and pinions. Two vernier scales show the degree of movement in each direction. Specimens are held on the stage plate between two sliding brackets. The substage condenser can be focused and is fitted with an iris diaphragm. The plano-concave mirror is set in a horseshoe mount below the condenser. The instrument has a wooden carrying case that also holds six eyepieces.
