French Navy Reflecting Circle by J. Angele N°1136

French Navy reflecting circle of brass with inlaid silver scale divided from 0 to 180 degrees on either side of the zero point and signed "J. ANGELE N°1136 " on the arc, with the additional mark "SH 1136" on the index arm. The original dove-tailed fitted mahogany case with brass hardware also bears the brass tag reading "Service Hydrographique Circle Hydrographique J. ANGELE N°978 ." This instrument, with folding turned hardwood handle, was obviously used in the French Hydrographic Service for charting and mapping.
