Description: Yes, hard times, BUT The country & city lives and the postal service works well. The KL-1 circular logarithmic ruler is designed to perform the most common mathematical operations in practice: multiplication, division, combined actions,squaring, extracting the square root, finding trigonometric sine and tangent functions, as well as the corresponding inverse trigonometric functions,calculating the area circle.The slide rule consists of a case with two heads, 2 dials, one of which rotates with a head with a black dot and 2 hands that rotate with a head with a red dot. There is a fixed pointer against the head with a black dot above the moving dial.On the moving dial there are 2 scales: internal - main - countable and external - scale of squares of numbers. On a fixed dial there are 3 scales:the outer scale is a countable analogous to the internal scale on a moving dial, the average scale is of "S"-values of angles for counting their sines and the inner scale of "T" -values of angles for counting their tangents.The lid of the box has a crack, the box is scuffed.English & Russian manual included.Great gift !
