1744_GUNTER_Scale

This is a copy of the very old scale invented by Edmund GUNTER (GB) in the 17th century (1623). This scale was the precessor of the sliderules: It has no slide, but many scales, among them one being logarithmic. Calculation is done using the compass (divider) shown below the case. The lower pictures shows the backside. The age of this "copy" is unknown, it could be ~1800, or probably a much more recent copy; the wooden case surely is much more recent, and not an original.
