Weinmann was located in the city of Schaffhausen and is a large Swiss manufacture of bicycle parts and supplies many bicycle firms. During the 1930-1970s Weinmann supplied rims, both tubular racing and clincher type city rims. They also made side pull and center pull brakes. The 1930s and into the early 1950s side pull were quite common for racing use. By the mid 1950s Weinmann was manufacturing their famous Weinmann Vainqueur Model 999. The set on the left show the name anodized onto the face of the caliper. These brakes required front and rear cable guides/stops which often came with a quick release mechanism that is handy for easier tire removal.
