Bio:
"This little combination magnifier may be the most common antique microscope ever available. It also may have the most alternative names! In its most basic form, that shown on this page, it had only a slit on the side to accomodate the pin. A slightly more useful design included a larger opening that could accomodate a small vial for liquid-containing specimens. Later, a swivelling mirror and a horizontal slot for small slides was provided. The original form was offered in French advertisments as early as 1851, and in English ads as early as 1885, but was featured in the Pan American Exposition, a Worlds Fair of 1901. This instrument and its variations continued to be sold through at least most of the second quarter of the twentieth century. Many merchants sold this either via their catalogs, at exhibitions (fairs), or via mail through magazine advertisements. This non-achromatic magnifier of cheap constuction, should not be confused with the superficially similar, but much higher quality simple microscopes of the period…"
