Technofix made tin toys, comic and erratic action litographed tin wind-ups. Prior to 1930s, their toys can be identified by the initials GE or GEN. The company was founded by the Einfalt brothers Georg and Johann in Nuremberg, Germany and existed from 1922 to 1977.
The brothers Einfalt continued to produce tin toys in the west under the name of 'Technofix' and many of their toys were marked 'Made in the U.S. Zone Germany'. The tin toys produced in this period reflected the technical and scientific advances. As new transport vehicles like cars had replaced horsedrawn ones, new toys appeared that reflected interests in new technologies and innovations like for example space technology, land-speed records and new car designs.
The toy industry found it had to respond quickly to these changes and new models were designed and manufactured in a short time and cheaply. One of the results was the replacement of clockwork and wind-up mechanisms with cheaper friction motors.
