Holland Circle by Baumann and Kinzelbach
This intriguing item is almost certainly a Holland Circle by German scientific instrument makers Baumann & Kinzelbach. The Holland Circle, sometimes referred to as a Dutch Circle, was used in land surveying and is a precursor to the theodolite, an optical instrument for measuring angles. Baumann and Kinzelbach were based in Stuttgart, Germany, and in addition to crafting surveying instruments and compasses, also created a 2-foot tall "comet seeker" used at the Gotha Observatory near Gotha, Thuringia, Germany. Crafted from bronze with a handsome wooden stand and complete with its custom carrying case, this finely-calibrated instrument is a unique and elegant piece of scientific history.
