In the late nineteenth century, Bausch & Lomb began making Continental stands like those to be had from such Europeans firms as Hartnack, Zeiss and Leitz. These featured a horseshoe base and a relatively short optical tube. This example, which is of that sort, is a compound monocular with coarse and fine focus, double nosepiece (missing one objective), square stage, inclination joint, and sub-stage mirror. An inscription on the nosepiece reads “BAUSCH & LOMB OPT. CO. / ROCHESTER, N.Y.” A brass tag on the base reads “T - / 8832.” It dates from around 1890, and may have been an experimental model.
