Unfortunately, I cannot make any statement about the manufacturer of your model. This model is unfortunately not known to me.
With the "big brother" I meant an old screw press that was in the locksmith's shop where I worked part-time about 30 years ago.The locksmith's shop was still partly equipped with machines as in the 1920s. There was even a transmission that was driven by a large electric motor.
