Brass Violin String Gauge

This rare tiny brass Violin String Gauge has markings on one side that read Violin C.F Albert, String Gauge in 5 TH5 Pat March 1812 or 1815 – the last number is hard to read. It has four gauges numbered 1, 2, 3, 4 on each of three sides. On the left-hand side is the letter D, on the right-hand side is the letter E and on the lower side are the letters A G. The back of the gauge has no marks. The photos show scratches but these can hardly be seen to the naked eye. It is in excellent condition with no damage.
