|This is a compass with map reader made between 1950 and 1960. The compass is in working order and the map reader is working fine.

The movement of the needle on the dial will allow to measure the distance by following the instructions on the paper. There are two scales: centimetres to kilometres and inches to miles. The instrument is housed in a fine leather case that is still in excellent condition. Instrument in overall good condition.
