Physical DescriptionMiniature Tabletop Refracting Telescope. Ground and polished glass lenses, rolled brass; assembled. This compact, all brass outfit arrives as a rather solid brass cylinder. Removing the single draw tube, the tripod and pillar assembly is found stowed inside, and unscrews. The pillar then reverses, the head dovetails into a slot on the main tube, the dust cover unscrews, and we have a full tabletop instrument. The objective is apparently a biconvex singlet, and there are four selectable eye lenses on a rotary wheel. The draw tube is engraved with four corresponding focal positions.Provenance
