Wild Heerbrugg produced Precision Drawing Sets of Stainless Steel sets between 1942 and 1972

Wild Compasses are not merely chromium plated. They are made out chromium containing stainless steel. Stainless steel is five times more resistant than Brass or German Silver. Even perspiration and eraser particles, which so quickly turn any other metal drab, can not discolor chromium steel. The instruments always retain their beauty. The design of the WILD Compasses affords quicker and more accurate settings because, as the opening of the compass is set, thanks to the careful adjustment of the leg articulation, there is no lateral play or backlash. The WILD drawing pens are hardened by a special process. They are finished to such a high degree of precision that very fine or heavy lines can be drawn at will without any scratching or cutting, with a perfectly even flow of the ink. The handles are aluminum anodized, and can therefore resist tropical climates. The cases are of pressed metal.

Like new codition, rarely used !
