Nuttall dates this microscope to 1845-52 and refers to it as one of Dancer's first large models, possibly a prototype.
It is obviously influenced by the work of Hugh Powell and Peter Lealand, particularly the use of the curved limb and the Turrell-pattern stage. As far as it being a prototype Nuttall points to the use of three metals in its construction (gun-metal and two different coloured brasses) suggesting the use of availiable parts as opposed to pre-prepared castings. The Gilbert-pattern condenser appears to be a later addition due to evidence of alterations of the mechanics, as well as having been introduced some years later. Also a second mechanical stage has been added as the original has too small an appature for full use of the Gilbert.
Along with the surviving accessories are a few slides amateruly prepared in India and dated 1847.
